  • THE PROMISE DELIVERED: Inside the Partnership That Rebuilt a Legend

    THE PROMISE DELIVERED: Inside the Partnership That Rebuilt a Legend

    By Benjamin Allen and Ellie Allen

    The first note didn’t surprise me. It startled me.

    It was a low subtone, the kind you test almost without thinking, a reflex, a way of asking a new mouthpiece who it thinks it is. But this one answered before I finished the question. The sound bloomed immediately, warm and dense, the way the great vintage Florida Tone Edges sometimes do when you’re lucky enough to find one that isn’t warped, worn, or quietly fighting you. I sat back in my chair, the reed still vibrating. After decades of searching, refacing, measuring, and hoping, I knew the feeling. It was the feeling of something rare.

    In January, I had written about the unlikely partnership between Theo Wanne and JJ Babbitt (JJB), a collaboration that sounded promising on paper but carried the weight of a century of expectations. The manufacturing logic was compelling. The history was complicated. The question that mattered was the one I was now hearing in the air of my practice room. Could they actually do it?

    Two 7* Florida Tone Edges later, the answer was sitting in my hands. They are, without qualification, the finest Florida Tone Edge mouthpieces I have ever played. That includes every vintage original and every professionally refaced piece I have encountered across decades of searching, and as a former mouthpiece maker and refacer myself, that search has been extensive.

    But the story of how this sound came to exist began long before I ever played a note.

    The Problem They Inherited

    Five years before that first note bloomed in my practice room, the JJB factory in Elkhart was a place suspended between pride and fatigue. The company’s legacy was undeniable. Otto Link and Meyer are names that shaped the sound of American saxophone playing. But the day-to-day reality had drifted far from the mythology. Processes lived as undocumented habits, passed down like family stories. Quality depended on who happened to be standing at which bench on which day.

    Inside the building, the workers were doing everything they knew how to do. Outside it, the industry had begun to whisper. The gap between effort and perception widened until it became impossible to ignore. And when that truth finally reached the people on the floor, it hurt. They had been working in good faith for years.

    This is the part of the story most companies would bury. But Steve Rorie didn’t bury it. He walked straight into it.

    When he took the helm, he inherited not just a manufacturing operation but a culture shaped by decades of improvisation, the kind that works until it doesn’t. He could have chosen the easy path, a marketing refresh, a few cosmetic changes, a press release about renewed commitment. Instead, he chose honesty. He acknowledged the gap. He told the truth about what needed to change. And then he began the slow, unglamorous work of rebuilding a foundation that had eroded quietly over time. What he has built works because of the people he brought together and the way he lets them shine.

    The People Who Made It Happen

    Members of both the Theo Wanne and JJB leadership and teams were kind enough to share with me a detailed account of how the project came together and who drove it forward. It is not the story of a corporate announcement. It is the story of two groups of skilled and dedicated people who found in each other the missing half of a problem they had each been trying to solve.

    On the JJB side, Phil Hobson and Alexis Schooley have been equal partners in the manufacturing transformation, working hand in hand to develop what might be called the Babbitt ingredient. Phil approached it from a machinist and mechanical perspective, rebuilding a process that had existed almost entirely as institutional memory, decades of accumulated tribal knowledge with nothing written down, from the ground up through sheer rigor and work ethic. The quality improvements players began noticing in the more recent metal Links trace directly to his efforts. Alexis brought the artisan’s perspective to the hard rubber line, mastering entirely new processes and taking genuine ownership of the team around her. Theo, who has worked with mouthpiece craftspeople across his entire career, has said that Alexis is among the very best he has encountered. Together they have built something neither could have built alone, and the working relationship that developed with the Theo Wanne team has been driven entirely by shared goals rather than competing egos. Steve’s son Trace, a Leadership Development specialist, has nurtured, mentored, and motivated JJB’s three-person production management team into the cohesive unit the project required. That team includes Stephanie Ryman, who oversees the plastic and OEM side of the operation, rounding out a production leadership structure that is quietly as important as anything happening at the bench. Chris French rounds out the JJB core in a way that defies easy summary. He is a world-class saxophonist and clarinetist on faculty at Notre Dame, but also someone with deep hands-on experience in tooling, fabrication, and CAD design, a rare combination of artistry and engineering that made him invaluable at every stage.

    On the Theo Wanne side, the effort was all hands on deck. Theo brought not just his deep knowledge of Link history, geometry, and acoustics but the clarity of vision to define what the project needed to be and the leadership to see it through. Bryan Vance, Theo’s COO, hammered out the business and logistical architecture of the shared-ownership partnership while contributing substantive player feedback throughout the refinement process. Thomas Harris, a world-class player in his own right, handled nearly all of the facing and calibration work and was a central presence during the design process. Matt Ambrose, whose work I have written about previously in the context of material behavior and CNC precision, served as master machinist and lead CAD specialist, translating design intentions into the physical geometry the player ultimately encounters. Sean Wheeler brought deep process development experience alongside serious machining skill, working through iteration after iteration of the approach while also shouldering the less visible but equally critical work of quality control. Justin Maurer, whose grandfather Bob Carpenter was one of Theo’s earliest mouthpiece mentors and whose connection to this project carries a quiet thread of continuity, handles all of the Theo Wanne website, photography, social media, and advertising, and has begun extending that work to JJB as the partnership grows. His wife Stephanie Pierce managed inventory, assembly, fulfillment, and shipping. Machinists David Nelson and Mitch Buss kept the machines running nearly around the clock.

    Everyone contributed. Having now played the result, I believe it.

    I have had the privilege of knowing Theo and his team for many years, and in every interaction they have been among the most technically rigorous and genuinely honorable people in this industry. Steve Rorie’s decision to engage so deeply with them reflects real vision. Bringing that level of integrity and technical mastery into the JJB family is, in my view, one of the most consequential strategic decisions in the modern history of Otto Link, Meyer, and JJB. I am their biggest fan, and I am not kidding.

    What the Otto Link Florida Tone Edge 7* Actually Does

    The Florida Tone Edge 7* plays with an immediacy I have not experienced in a stock Link mouthpiece before.

    Response across the full dynamic range is exceptional. The facing geometry is precise enough that the reed-to-table relationship is consistent and predictable, and you feel that immediately. The mouthpiece does not fight you at low dynamics and does not spread or destabilize at high ones. Subtone is effortless. The low-frequency response is present without requiring embouchure manipulation to find it. The altissimo register speaks with surprisingly little resistance, a direct consequence of a well-executed facing curve and consistent tip rail geometry.

    Tonally, the character is exactly what the Florida Tone Edge was always meant to be. A thick, warm core with genuine low-frequency depth, and above that a layer of upper-harmonic presence that gives the sound life without tipping into gratuitous brightness. It has the kind of tonal density that fills a room without shouting, with just enough upper-frequency sparkle to remain present and defined in a band context. Most importantly, the tone is continuous, one voice across the full range of the horn, not three separate registers negotiating with each other.

    What separates this from the best vintage pieces I have played is not that it sounds different. It is that it sounds like what the best vintage pieces sounded like, reliably, without having to hunt for the rare one that happens to be right. The CNC-machined facing and internal geometry mean the mouthpiece is not a fortunate accident of an inconsistent manufacturing process. It is the result of people who knew exactly what they were trying to achieve and had the tools, the skill, and the commitment to achieve it.

    That reliability is the revolution.

    A New Chapter in a Long Story

    The vintage Florida Tone Edge and the original Slant Signature produced some of the most iconic saxophone sounds in recorded jazz history. They also produced a great deal of inconsistency, and the search for a truly great one has occupied players and collectors for generations.

    When I finally set the horn down after playing these mouthpieces, the room was quiet in the way rooms get quiet after something important has happened. The sound was still hanging in the air, but the realization was louder. This mouthpiece wasn’t an accident. It was the product of a partnership built on honesty, rigor, and character.

    I have since ordered the full range, the STM, STM Florida, Tone Edge, and New York Tone Edge, and I will write about each as they arrive. But if the Otto Link Florida Tone Edge is any indication of what this partnership has achieved across the line, the saxophone world is in for something remarkable.

    When I shared these impressions with Steve Rorie directly, his response said something I think belongs in this essay. In his words:

    “I also am grateful for your personal insights regarding Theo and his team. We have found exactly the same things with regard to their experience, skills, talent and creativity. But what we love most about them all is their character, integrity and their hearts. My son Trace and I knew early in our partnership discussions with Theo, that the coming together of TW and JJB had the makings of exactly what you stated, potentially the most significant chapter in the legendary history of Meyer and Otto Link. The partnership is just getting started but the early signs are encouraging and even quite exciting. But one of the key elements remains hearing from and responding to as well as incorporating input from professionals like you.”

    The search for the great Otto Link Florida Tone Edge, the mythical piece that plays the way the legends played, may finally be over. Not because someone found one, but because a group of people decided to build one together, with intention, with honesty, and with the kind of character that turns a manufacturing partnership into something that actually matters.

    That last sentence of Steve’s is worth sitting with. This partnership is not a finished product. It is a living collaboration, and player feedback is not peripheral to it. It is part of how it moves forward. If you are playing one of these mouthpieces, your experience is worth sharing.

  • SYOS, Extraordinary Science, and Unresolved Questions

    SYOS, Extraordinary Science, and Unresolved Questions

    The announcement of a titanium mouthpiece from SYOS has captured the attention of many within the saxophone community. That response is understandable. SYOS occupies a position unlike any other company in the mouthpiece market, and a move into laser metal fusion titanium represents a meaningful departure from everything that defined them at their founding. It is an occasion worth examining carefully, not simply as a product announcement, but as a window into a company whose strengths and contradictions are both substantial.

    I have followed SYOS since their early years and have held consistent views about them, some admiring and some critical. The titanium piece sharpens all of those views simultaneously. What follows is an attempt to take stock of SYOS honestly, as a company, before the hype of a new product displaces the analytical work that the moment actually calls for.

    This essay was shared with SYOS prior to publication. Their response is documented in the Marketing Problem section below.

    The Foundation

    Pauline Eveno and Maxime Carron founded SYOS in 2016, two acoustics researchers trained at IRCAM in Paris. IRCAM, the Institut de Recherche et Coordination Acoustique/Musique, is among the most respected institutions in the world for the study of acoustics and sound technology. A marketing credential it is not. IRCAM represents a research pedigree.

    Eveno’s doctoral work focused on wind instrument acoustics. Carron’s background was in auditory perception and psychoacoustics. The combination was deliberate and productive. One founder understood how the geometry of a mouthpiece shapes the acoustic behavior of the air column, and one understood how players perceive and describe sound. That pairing is the intellectual core of what SYOS became.

    Their design methodology reflects that foundation. SYOS works with a stated precision of one one-hundredth of a millimeter, modeling the acoustic effects of baffle height, chamber volume, facing length, and tip opening as independent variables with predictable relationships to tonal output. Traditional mouthpiece craftsmanship does not speak this language. Acoustic engineering does, applied here to an instrument the broader market had largely treated as immune to rigorous analysis.

    SYOS engineered their proprietary material, known as UPSCAL3D, in collaboration with French research laboratories specifically for additive manufacturing. They designed it to replicate the acoustic density of hard rubber while exceeding it in durability and UV resistance. Developing a purpose-built material, rather than adapting an existing polymer, signals the seriousness with which SYOS approached the manufacturing problem.

    This is the foundation on which everything else rests. Before any evaluation of their commercial practices, their marketing, or their strategic decisions, it is necessary to understand that SYOS built this on something real.

    The Artist Catalog

    The scale of SYOS’s artist collaboration program is, by any reasonable measure, remarkable. With a self-reported community of over 30,000 musicians worldwide, their Signature collection reflects a breadth that no comparable company has achieved.

    The roster spans multiple genres and generations. Jazz figures such as Tivon Pennicott, Shabaka Hutchings, Greg Osby, Patrick Bartley, Joe Lovano, Jeff Coffin, and Lihi Haruvi have collaborated with SYOS on signature pieces. So has Michael Wilbur of Moon Hooch, whose high-energy approach showcases the material’s durability, along with Scott Page of Pink Floyd and Toto. Ted Nash, whose recent titanium prototype video represents SYOS’s most recent public artist engagement, bridges compositional and improvisational worlds.

    The acoustic data implicit in that catalog is not trivial. Over 200 professional collaborations represent a dataset of tonal preferences and geometric feedback that no other mouthpiece company in the world currently holds at comparable scale. Each collaboration presumably involves feedback on geometry, facing, baffle, and chamber characteristics from a player with a developed and documented sound concept.

    The Signature model itself is acoustically interesting as a commercial proposition. It offers players not a generic mouthpiece with an artist’s name attached but a piece whose geometry was actually developed in collaboration with that artist and calibrated to their stated tonal preferences. Whether the resulting mouthpiece translates to any individual buyer’s embouchure and vocal tract is a separate question, but the underlying premise is more honest than most artist endorsement arrangements in the instrument market.

    For these reasons, I stand by the claim that SYOS has built an intellectual capital that is without parallel in the modern boutique mouthpiece market.

    Two Reservations

    My admiration for the SYOS research profile has coexisted with two specific reservations, both grounded in hands-on evaluation rather than speculation.

    The first concerns material feedback. I have played on hard rubber and metal mouthpieces since I began playing the saxophone, and when I first 3D printed pieces of my own for design evaluation purposes, the tactile feedback of the material was immediately atypical. The vibrational characteristics transmitted through the polymer felt different from what I had accumulated as a reference point over years of playing. I now attribute this more to unfamiliarity than to any acoustic deficiency in the material itself, which places it squarely in psychoacoustic territory. It was the perception of an unfamiliar physical sensation and not a measurable change in radiated output. Any downstream effect on radiated output would be mediated through the player’s response to that sensation, not through the material’s acoustic properties directly. The psychoacoustic dimension of this experience, and the broader question of how the player functions as a variable within the acoustic system, is examined in depth in The Primacy of Response.

    That said, I did not find the resulting tonal output from 3D printed pieces to be especially distinct from conventional materials in ways that matched the strength of the marketing claims surrounding them. Given Carron’s background in auditory perception, it is curious the brand spent years treating these sensory reference points as secondary to geometry.

    The second reservation is practical. The aesthetic of the SYOS polymer product, often characterized by visible layer lines and a raw matte texture, gives the impression of a prototype rather than a finished professional tool. While SYOS defends this as a byproduct of their additive process, the market now contains a direct counter-argument in the Theo Wanne Essential Line. Wanne’s additive manufacturing process utilizes a proprietary bio-polymer that can yield a surface finish nearly indistinguishable from traditional machined hard rubber mouthpieces. Furthermore, it is my understanding these pieces can be manufactured to something just short of mirror-smooth tables and high-gloss aesthetics to meet boutique expectations. Prioritizing internal geometry and achieving a refined surface finish are not mutually exclusive, and this comparison suggests SYOS’s raw appearance is a conscious choice rather than a manufacturing necessity, one that may be becoming an unnecessary liability.

    Both of these reservations apply specifically to the 3D printed polymer product, which professional players at the highest levels have nonetheless adopted. They do not apply to titanium.

    The Marketing Problem

    The scientific credibility of SYOS’s founding and the seriousness of their research program make their marketing practices more difficult to understand, not less.

    I have documented, across two published pieces on this site, a pattern of SYOS using the images and identities of deceased saxophone legends in sponsored social media advertising. In campaigns for the Smoky and Spark, SYOS has invoked the likenesses of Stan Getz, Paul Desmond, David Sanborn, and Michael Brecker, but these players have neither endorsed SYOS nor played their mouthpieces. Getz and Desmond played on specific equipment that the saxophone community has documented and studied extensively. Brecker and Sanborn built their respective sounds on setups that are well known to anyone with serious interest in their playing and gear histories.

    To invoke these players in advertising for a product they never touched is not simply misleading. The advertisements paired photographs of these players with copy promoting specific SYOS tonal profiles, implying an acoustic lineage that does not exist. Such a practice is a misappropriation of artistic identity that the saxophone community has every right to scrutinize.

    The pattern is not limited to paid advertising. SYOS’s own About Us page asks visitors whether they are looking for a smooth, mellow Stan Getz sound and whether they are a fan of Brecker, Sanborn, or Steve Lacy. These are tonal aspirations attributed to deceased players, invoked directly in the company’s core marketing copy, on their own website, without qualification.

    Sponsored SYOS advertisement featuring Stan Getz and Paul Desmond
    Sponsored SYOS advertisement featuring Stan Getz and Paul Desmond promoting a SYOS tonal profile.

    The contradiction at the center of this practice is not subtle. A company founded by two IRCAM-trained acousticians, whose entire value proposition rests on the claim that geometry determines sound, is simultaneously running advertisements implying that the sounds of deceased legends can be replicated through their products. Either geometry and acoustic science determine the sound a mouthpiece produces, in which case the identity of a player who never used the product is irrelevant to the buyer’s decision, or the famous player’s identity is the actual selling point, in which case the acoustic science is decoration. Both positions cannot be held simultaneously without undermining one of them. The acoustical basis for this argument is developed more fully in The Primacy of Response, which explains why a mouthpiece’s tonal output is practically inseparable from the player producing it.

    SYOS maintains a legitimate and apparently well-functioning endorsement program with living artists. They know how to obtain actual consent. The decision to supplement that program with deceased players whose estates may or may not have authorized the use of their images represents a conscious choice, and it is a choice that sits in direct tension with the scientific credibility they have worked to build.

    I submitted a pre-publication draft of this essay to SYOS on May 4, 2026 and received an automated customer service acknowledgment. No substantive response followed.

    The Titanium Question

    The SYOS titanium mouthpiece, which launched on May 5, 2026, is the most interesting thing the company has announced since its founding. Produced via laser metal fusion, an additive manufacturing process that builds objects layer by layer from metal powder using a high-powered laser, it addresses both of my reservations directly. Titanium’s vibrational characteristics offer a tactile framework that serious players already understand from other metal mouthpieces and instrument components.

    There is also a credible case that additive manufacturing, at its current state of development, can achieve mouthpiece tolerances and specifications that meet or exceed what conventional machining is capable of producing, which positions SYOS’s existing expertise in additive processes as a genuine competitive advantage rather than a limitation.

    The acoustic case for titanium in mouthpiece construction is not settled science, but it is a serious conversation. Titanium’s stiffness-to-density ratio and damping characteristics differ from brass, bronze, and hard rubber in measurable ways. Whether those differences meaningfully affect the player’s vibrational perception and playing response, and whether any such effect propagates through to radiated acoustic output, is precisely the kind of question that a company with SYOS’s research infrastructure is better positioned to investigate than almost any other entity in the market.

    The limitation to 100 units, however, raises a strategic question that the announcement does not answer. For a self-reported community of 30,000 musicians, a 100-unit production run represents a service rate of 0.33 percent. Two interpretations are available. The first is market testing, where SYOS assesses demand, gathers player feedback at the professional level, and determines whether a broader titanium program is commercially viable before committing to the manufacturing investment it would require. The second is deliberate scarcity positioning, with 100 units offered as a luxury artifact designed primarily to elevate the brand’s market position rather than serve the community at scale.

    Neither interpretation is necessarily damaging to SYOS as a company. Market testing is rational. Premium positioning is a legitimate strategy. But the two interpretations carry different implications for the saxophone community’s relationship with the product. If this is a proof of concept on the way to a production line, the excitement is warranted. If it is a permanent ceiling, the community is being managed rather than served.

    SYOS would very likely crush it if they expanded production in this direction. With their IRCAM-grounded research methodology, a design catalog without parallel in the boutique market, and over 200 professional artist collaborations generating acoustic data no competitor holds at comparable scale, they are better positioned than any other company to lead the mouthpiece market into laser metal fusion. That is the version of this announcement that would match the scale of their intellectual capital.

    Conclusion

    SYOS is a company of genuine contradictions, and those contradictions are worth taking seriously precisely because the company itself is serious.

    The scientific foundation here is not marketing copy. Real acousticians staff a genuine research program, producing mouthpieces whose design methodology is more rigorously documented than anything else currently available in the market. The artist collaboration catalog is extensive, multi-genre, and acoustically substantive in ways that no competitor has matched. Their customer service model, which involves iterative physical refinement until the player is satisfied, is genuinely differentiated. And they are continuously collecting acoustic and preference data across thousands of interactions. The intellectual capital SYOS has accumulated since 2016 is, by any honest assessment, without parallel in the mouthpiece industry.

    That is precisely what makes the marketing contradiction more puzzling, not less. A company with this much genuine intellectual capital, this level of customer service investment, and this depth of research infrastructure does not need Brecker’s photograph or Desmond’s image in a paid advertisement. Their own story is stronger than any posthumous association they could manufacture. The fact that they reach for those associations anyway suggests either that the marketing arm is operating independently of the research and customer service culture, or that they do not trust their own legitimate story to sell the product.

    The titanium piece is the clearest expression yet of what SYOS could become if their commercial strategy caught up with their research profile. Laser metal fusion titanium resolves the material questions that 3D printed polymer left open. The geometry-driven design methodology, applied at titanium’s precision, represents a genuinely interesting frontier in mouthpiece development.

    Whether the 100-unit limitation is a first step toward a production program or a ceiling in itself is the question that will determine whether the excitement is warranted. SYOS has the science, the artist relationships, the customer service infrastructure, and the design catalog to become a transformative force in the mouthpiece market. Whether SYOS becomes a research-led mouthpiece company or a research-themed lifestyle brand is the choice now in front of them.

  • SYOS Is Still Using Dead Legends to Sell Mouthpieces

    SYOS Is Still Using Dead Legends to Sell Mouthpieces

    Three weeks ago, I documented a pattern. SYOS was running sponsored social media advertisements featuring black and white images of legendary saxophonists to promote their products. The players in those ads were Michael Brecker and David Sanborn. Neither endorsed SYOS. Neither played SYOS. Sanborn spent the better part of his career on a Dukoff 8 Metalite. The full analysis is here.

    SYOS has continued.

    A new sponsored advertisement is now circulating featuring Stan Getz and Paul Desmond. Both are deceased. Neither played a SYOS mouthpiece. The ad copy promises “a dark, warm and deep tone.”

    This is worth pausing on.

    Screenshot of a sponsored SYOS advertisement featuring Stan Getz and Paul Desmond
    Screenshot of a sponsored SYOS advertisement circulating on Facebook, May 2026.

    Desmond’s tone is arguably the most mythologized in alto saxophone history. It has been analyzed, chased, and never successfully replicated through equipment choices, not even by players who have tracked down his exact setup. The consensus among serious players and acousticians is that his sound was the product of an unusual embouchure and air approach that no mouthpiece geometry can reproduce.

    Getz presents a similar problem. His warm tenor sound lived in breath support, vowel shaping, and an unusually flexible vocal tract, not in facing curves or chamber dimensions. To place either of them in an advertisement premised on equipment-driven tone is not just misleading. It is acoustically illiterate.

    SYOS Advertisements Go Beyond Social Media

    SYOS’s own product pages invoke deceased artists by name. The Tenor Spark page describes it as producing “Michael Brecker’s style of sound.” The Tenor Smoky page describes it as perfect for “jazz ballads with Stan Getz’s style of sound.” Brecker and Getz are both deceased. Neither endorsed SYOS. Neither played one. That language lives permanently on their website, attached to products, in a context that any reasonable consumer would interpret as implied association with two of the most technically admired saxophonists in history, an association SYOS has not earned and, to my knowledge, has no basis to claim.

    What makes this particularly difficult to excuse is that SYOS does have a legitimate artist endorsement program. Living players including Jimmy Sax, Scott Paddock, and Knoel Scott have documented signature mouthpieces on the SYOS website with their names, their words, and their actual equipment specifications. SYOS knows how to obtain a real endorsement. They have chosen, in parallel, to run campaigns built around deceased legends who never consented to any association with their products.

    That is not an oversight. It is a strategy.

    A Strategy That Contradicts Their Own Claims

    It is also a strategy that sits in direct contradiction to SYOS’s own stated identity. The company was founded by two acoustics researchers with PhDs and markets itself heavily on its scientific credentials and its roots in IRCAM research. A company whose founders understand acoustic science at that level knows, or should know, that Paul Desmond’s tone cannot be traced to mouthpiece geometry. They know that Stan Getz’s sound lived in his body, not his equipment. Deploying those names in equipment advertising is not a scientific claim. It is the opposite, a deliberate appeal to mythology from a company that has built its brand on rejecting mythology.

    Readers who have concerns about the use of deceased artists’ names and likenesses in commercial advertising without documented permission may wish to consult the FTC’s published guidance on endorsements, as well as applicable right of publicity laws, which vary by jurisdiction and in some cases extend beyond the artist’s death. I am not a lawyer and nothing here constitutes legal advice. But I am a member of the saxophone community, and I can read an advertisement.

    SYOS is the only company currently running this kind of campaign. Other makers, including those who produce custom and 3D-printed mouthpieces, cite living artists who actually use their products. They document design decisions. They do not borrow the faces and names of legends to imply a lineage that never existed.

    At this point the pattern is clear and it is deliberate. A warning was issued and ignored. The saxophone community deserves better than this, and SYOS knows exactly what it is doing.

    For a fuller assessment of SYOS as a company, including their scientific foundation, artist catalog, and the contradictions that complicate both, read SYOS, Extraordinary Science, and Unresolved Questions.

  • The Pop Test Is Not Optional

    The Pop Test Is Not Optional

    There is a test you can perform on your mouthpiece in ten seconds. It costs nothing. It requires only a wet reed, your mouthpiece, and your own breath. It tells you whether the reed is sealing against the table, which is one of the most basic conditions for stable acoustic performance. The test is called the pop test. A surprising number of players have decided that it is beneath them. This essay is an attempt to correct that.

    What the Test Is

    Wet the reed and seat it on the mouthpiece with your usual ligature tension. Seal the bore end against the center of your palm. Draw the air out through the tip to create a vacuum. Remove your lips. If the reed is sealing against the table, the vacuum holds briefly and the reed releases with a pop. If air rushes in immediately, the seal is compromised.

    That is the entire procedure. You are verifying that the flat back of the reed is making contact with the flat table of the mouthpiece. When it does not, air leaks through the gap. When air leaks where it should not, acoustic efficiency drops.

    One clarification matters. The pop test is primarily a reed diagnostic. Most failures come from warped or uneven reed backs. When you use a reed you know to be flat, the test becomes a direct indicator of whether the table and reed are sealing. That narrower use is the one that matters.

    Why the Seal Matters

    The reed and facing form a valve. The reed vibrates open and closed at the frequency of the note being produced. The table is not part of the vibrating system. It is a seating surface. Its job is to give the reed a stable plane from which to vibrate.

    When the table does not seal, a secondary air path exists. The instrument still plays, the reed still vibrates, and the column still resonates. But the system is less efficient. The cost is not primarily volumetric. When the reed closes against the table, it creates the impedance boundary that reflects the traveling pressure wave back down the bore. A gap at that boundary degrades the reflection. Wave reflection is sensitive to boundary sharpness, not to the volume of air that escapes. These are different physical phenomena with different tolerances, and a leak too small to matter for airflow can still matter for acoustic efficiency. The player compensates without realizing it by increasing embouchure pressure and adjusting air support, which shifts the reed. These compensations become habitual, and the player adapts to the leak instead of eliminating it.

    This is why the pop test matters. A leaking mouthpiece is not unplayable. It is simply more work than it needs to be. The player pays the cost without knowing there is a cheaper alternative.

    The Arguments Against the Test and Why They Fail

    The objections that follow are not entirely frivolous. Some contain a partial truth. None of them is a reason to abandon the test.

    “I have mouthpieces that fail the test and play great.”

    This objection confuses two different questions. Passing the test does not guarantee good playability. Failing the test does guarantee a leak. These are not the same thing. A mouthpiece can fail the test and still produce a sound the player enjoys. That does not mean the leak is harmless. It means the player has adapted to it.

    “It only tests the reed.”

    This is partly true and often misused. The test reflects the combined condition of the reed, the table, and the ligature. A warped reed will fail on any table. An over-tightened ligature can distort the reed. These are confounds, not reasons to discard the test. Use a reed you know to be flat. If the mouthpiece still fails across multiple reeds, the table is the likely cause. That is diagnostic information.

    “My embouchure covers any gap up the lay.”

    The embouchure does provide a secondary seal along the sides of the reed. Small imperfections near the ligature are often irrelevant. The table is different. It sits behind the facing curve, well outside the area the lips cover. A gap at the table is not compensated by embouchure placement. This argument applies a true observation to the wrong location.

    “The test damages reeds.”

    There is no evidence for this. I have performed this test before every playing session for thirty five years. My first serious saxophone instructor, who trained me at the New Orleans Center for Creative Arts (NOCCA), has performed it multiple times per practice session for more than fifty years and reports the same result. Not one reed was damaged. Three additional DMA and MFA level saxophonists and professors I consulted recently represent more than one hundred fifty years of combined playing experience among them. All perform the test routinely. None has ever damaged a reed doing it. A claim that has never materialized across that much accumulated professional practice is not a caution. It is a myth.

    “Just play test it.”

    The play test is the final criterion. Nothing in this essay disputes that. A mouthpiece that plays beautifully is working. But the play test and the pop test answer different questions. The play test tells you how the setup performs in the moment. The pop test tells you whether a specific physical interface is sealing. A mouthpiece can play acceptably with a slightly warped reed and still be operating below its potential. The pop test reveals that before you invest time adapting to the flaw.

    One qualification is worth making honestly. A skilled refacer evaluating their own work with calibrated facing curve measurements against a reliable target is operating in a specific professional context where the pop test may genuinely be redundant. That is a reasonable position for that workflow. It does not generalize to the player who lacks facing curve tools and is trying to determine, before a rehearsal, whether a reed and table are sealing.

    “It feeds the gear acquisition cycle.”

    The opposite is true. A player who suspects their mouthpiece is underperforming has two options: buy a new one, or run a ten second diagnostic that might reveal the problem is a warped reed, correctable for free. The pop test points toward a fix on equipment the player already owns. It is far more likely to interrupt unnecessary purchases than to encourage them. The concern that some players might misuse the test to discard a good mouthpiece is an argument for understanding what the test measures, which is the purpose of this essay. It is not an argument against the test itself.

    “It is only one variable.”

    This objection sounds practical but functions as anti-intellectualism. Playing involves many variables. That is not a reason to ignore one that is easily checked. Eliminating known problems is not a substitute for developing skill. It is a precondition for developing skill efficiently.

    “Respected refacers produce pieces that fail the test.”

    No craftsperson produces a perfect result every time. Materials vary. Tables wear. A mouthpiece that sealed when new may not seal after years of use. The pop test does not care whose name is on the piece. That is one of its strengths.

    What the Test Does Not Tell You

    It does not evaluate the facing curve. It does not determine whether the tip opening suits your reed strength. It does not judge chamber geometry. It does not predict dynamic behavior under vibration and moisture. It is a necessary condition check, not a sufficient one. Passing it eliminates one known source of inefficiency. Failing it identifies a correctable flaw.

    The Psychology of Resistance

    Once the acoustic objections fall away, something else remains. A meaningful portion of the resistance to the pop test is psychological.

    Some players resist it because it is simple. In a community that values expertise, a ten second test feels like a threat to hierarchy. Simplicity is mistaken for triviality.

    Some resist it because it threatens an investment. A mouthpiece that cost several hundred dollars should not be vulnerable to a test a beginner can perform. The test feels like an affront to the purchase, not a comment on physics.

    Some resist it because it threatens a narrative. A player who has built an identity around a particular setup does not want to consider that the setup has a correctable flaw. Dismissing the test is easier than confronting what a failed test implies.

    None of these are reasons to avoid the test. They are reasons to notice that resistance to a simple diagnostic is rarely about the diagnostic.

    A Note on Ligatures

    The test includes the ligature, and this is worth taking seriously rather than using as an excuse to dismiss the result. A ligature that applies uneven pressure or is tightened excessively can warp the reed and create gaps. But this is not a limitation of the test. It is an additional diagnostic layer.

    If you want to isolate the variables, perform the test twice. First, hold the reed against the table with firm thumb pressure alone, no ligature. If the mouthpiece seals under thumb pressure but fails when the ligature is added at normal tension, you have just diagnosed a ligature problem, not a table problem. That is information as useful as diagnosing a warped table, and it is available because you ran the test methodically rather than dismissing it. A mouthpiece that fails with one ligature and passes with another confirms the finding. The test did not mislead you. It told you exactly where to look.

    Practical Guidance

    Wet the reed fully. Use a reed you know to be flat. If the mouthpiece fails across multiple reeds, the table is the likely issue. A competent technician can correct it easily. If the mouthpiece passes with some reeds and not others, the reed is the variable.

    One edge case is worth knowing about. Occasionally a reed will fail the test not because the back is warped but because the cane itself is porous. Lower quality cane or certain cuts can allow the vacuum to escape through the fibers rather than around the edges. If a reed fails the test but its back surface is visibly flat and properly seated, leaky cane may be the cause. This is relatively uncommon but real. It does not undermine the test. It adds one more item to the interpretive checklist and further reinforces that the pop test is a diagnostic for the entire reed and mouthpiece system, not a verdict on any single component.

    Do not over-interpret the duration of the seal. A brief hold is a seal. A long hold is not a better seal. Duration reflects reed flexibility and moisture more than table quality.

    Conclusion

    In thirty five years of performing this test, I have never played a mouthpiece that failed it with a known flat reed and responded well. Every failure has correlated with poor response and instability. My first serious instructor, who trained me at NOCCA, has been performing this test multiple times per session for more than fifty years and reports the same finding without exception. Three additional DMA and MFA level saxophonists and professors, representing more than one hundred fifty years of combined experience, were unanimous. None has damaged a reed. None has ever played a setup that responded well while failing the test.

    That is not a controlled study. It is a consistent professional pattern with no counterexamples among the people consulted. It does not settle the question for everyone. It is evidence worth weighing.

    The pop test is not a complete evaluation. It is a check on one specific and acoustically meaningful condition. When it fails, there is a real physical problem. When it passes, one known source of inefficiency has been eliminated. The objections do not survive scrutiny. The resistance is more often psychological than acoustic.

    The saxophone and clarinet community values careful thinking about equipment. The pop test belongs in that tradition. It is fast, free, repeatable, and falsifiable. Those are the qualities of a tool worth using.

    Wet the reed. Seal the bore. Draw out the air. If it pops, good. If it does not, you have learned something worth knowing.

  • Clarinet Ligature Trial: What We Found

    Clarinet Ligature Trial: What We Found

    I said in a previous essay that I hoped never to write about ligatures again. I meant it. But a recent set of blinded trials produced results specific enough to be worth documenting, and one finding in particular points toward a mechanism I have not addressed directly before.

    A Note on Limitations

    This was a careful informal trial, not a formal experiment. Two players is a small sample. We controlled what we could, including mouthpiece, instrument, reed, tension, and testing order, but we cannot rule out that other variables influenced our perceptions. The sensation we identified with one ligature is subjective and difficult to quantify. We did not record audio for acoustic analysis. The results are suggestive rather than conclusive, and replication with more players and more ligatures would be needed before drawing firm conclusions. That said, the consistency across two sessions and three repetitions per session gives us reasonable confidence that we were not imagining things.

    The Trial

    A friend and I completed two separate ligature trials several weeks apart. In the first, we compared four clarinet ligatures. In the second, we compared the same four and added a fifth, a Rose Gold Inverted Screw Bonade.

    For each trial, we played on the same mouthpiece, instrument, and synthetic reed. The mouthpiece and reed were as flat as we could achieve. We cleaned everything between trials, blindfolded ourselves, and repeated each test three times.

    The ligatures in the first session were an Ishimori Kodama II, an Ishimori Standard, a Selmer Paris two screw, and a D’Addario H. The second session included those same four plus a Rose Gold Bonade Inverted. One note: the D’Addario sat slightly lower on the reed and could not be aligned to the same reference mark as the others.

    Results

    Results were consistent across both sessions. Neither of us could hear any tonal difference among the ligatures, whether playing or listening to the other person play.

    However, both of us independently identified the Kodama II every time while playing, not by sound but by feel. It consistently produced a sensation we described as more “brilliant” or “radiant,” even though nothing changed audibly. We both felt pulled toward playing with more energy or enthusiasm while using it, though we consciously held back. This pattern held across both trials.

    Discussion

    The null result across four of the five ligatures is consistent with what I have argued in previous essays. Three inverted two screw band ligatures, the Bonade, the D’Addario H, and the Ishimori Standard, plus a conventional metal two screw ligature in the Selmer, produced indistinguishable results both acoustically and proprioceptively. These designs differ in material, mass, screw orientation, and band composition, yet none of those differences were detectable under controlled conditions.

    The Kodama II is the exception, and its structural distinctiveness points toward a mechanism worth examining carefully. It belongs broadly to the Rovner family in that it uses a wrap around band rather than discrete screws bearing against the reed, but it departs significantly from that template. The band is relatively thick leather rather than thin synthetic material, and the reed plate is a comparatively substantial wooden component rather than a thin synthetic pad.

    Where a thin synthetic Rovner style plate distributes contact broadly and with minimal mechanical character of its own, the Kodama’s wooden plate is thick enough to behave as a mechanical element in its own right. Wood has different stiffness and damping properties than metal or synthetic materials, and a thicker plate will transmit and reflect vibrational energy differently than a thin one. The player receives mechanical feedback through the mouthpiece, teeth, and skull, and a reed plate with those material and geometric properties is plausibly delivering a qualitatively different proprioceptive signal even if the radiated sound remains unchanged.

    Importantly, all ligatures were set to the same minimal tension across both trials. The Kodama II produced a consistent and reproducible sensation even at that threshold, which suggests the material and geometric properties of the wooden plate are sufficient to drive the effect without requiring differential clamping force.

    This is a meaningful distinction from the tonal claims ligature marketing typically makes. The Kodama did not sound different. It felt different. If that proprioceptive signal influences how a player manages embouchure, air, or oral cavity shape in response, then any effect on the radiated sound would be downstream of the player’s adjustments rather than a direct acoustic property of the ligature itself. The ligature remains mechanically passive. What changes is the quality of the feedback it delivers upstream.

    That is a more defensible and, I would argue, more interesting claim than what the market typically offers.

  • The Boston Sax Shop and the Vision of Jack Tyler: Why Focused Identity Creates Lasting Success

    The Boston Sax Shop and the Vision of Jack Tyler: Why Focused Identity Creates Lasting Success

    The Boston Sax Shop has become one of the most influential boutique saxophone brands in the world, and its success is inseparable from the vision and discipline of its founder, Jack Tyler. In an industry where many shops rely on traditional retail models and generic accessory lines, Tyler built something entirely different. He created a saxophone brand that blends elite craftsmanship, intentional design, and genuine community into a single coherent identity. The result is a business that resonates with saxophone players across the world and stands out in a crowded and often stagnant market.

    Tyler’s path to building that brand was not the story of a designer who stumbled into the saxophone industry. It was earned from the inside. He holds two degrees in saxophone performance, the first from the Cincinnati Conservatory of Music and the second a master’s degree from the New England Conservatory of Music in Boston. While completing that graduate program in 2011, he apprenticed in saxophone repair under master craftsman Ernie Sola. When he finished his degree, he faced a choice between moving to New York to pursue a performance career or remaining in Boston to open his own shop. He chose Boston, and the Boston Sax Shop emerged soon after. That dual formation as both performer and technician is the foundation of everything the brand has become. It is the reason Tyler’s approach to repair, product design, and brand identity carries a credibility that purely commercial companies cannot replicate.

    Design Philosophy

    Tyler’s design philosophy begins with a simple but powerful insight. Saxophone players do not only want functional equipment. They want products that feel personal, expressive, and aligned with the culture of the instrument. Instead of copying existing designs or relying on exaggerated acoustic claims, he focused on solving real problems with products that are honest, beautiful, and thoughtfully engineered.

    The Boston Sax Shop Superlative Ligature is the clearest expression of this philosophy. It began as a sketch on the back of a cocktail napkin at the NAMM show in 2018, drawing inspiration from three vintage designs, the Selmer two screw, the Magnitone, and the Harrison. After two years of prototyping and input from respected saxophonists, the result was a single piece body with a laser cut reed contact plate, an inverted two screw orientation, and a trapezoidal taper that follows the natural width of the reed. It does not rely on mystical language or inflated promises. It succeeds because it is mechanically precise, visually coherent, and built with the kind of attention to detail that saxophone players recognize immediately.

    This design sensibility extends across the entire Boston Sax Shop product line. The reeds, mouthpieces, Heritage Neck, Signature Reed Cases, Ambassador cases, Cloud strap, and accessories all share a unified aesthetic that feels modern and intentional. The reed line grew out of Tyler’s personal frustration with the available options. He wanted a hybrid cut that combined the projection of jazz reeds with the warmth and evenness of classical cuts, and he developed it in partnership with a leading French cane manufacturer. Nothing in the product line feels accidental or generic. Every item reinforces the identity of the brand. Tyler is not simply creating saxophone accessories. He is shaping a visual and cultural language for the saxophone community. Players do not just buy a ligature or a neck strap. They buy into a world that feels authentic, earned, and connected to the lived experience of the instrument.

    The Business Model

    The business behind the Boston Sax Shop reflects the same clarity. The shop is located at 107 Brighton Avenue in the Allston neighborhood of Boston and operates by appointment only, a deliberate choice that prioritizes quality of service over volume of foot traffic. Rather than functioning as a conventional walk-in retail space, the shop serves as a physical expression of the brand’s values, precision, attention, and respect for the instrument. The real engine of the business is the proprietary product line, the online presence, the artist ambassadors such as saxophonists Jerry Bergonzi, Chris Potter, Joshua Redman, and Walter Smith III, and the consistent design language that appeals to saxophone players across genres and continents. This model creates a level of resilience and scalability that traditional music retail cannot match.

    The Case for Focus

    The name Boston Sax Shop is an asset precisely because it is specific. Saxophone players respond to this brand because it was built by someone who understands their world from the inside, as a player, a technician, and a designer. The visual and cultural language Tyler has built for the saxophone community is impeccable, and the saxophone market has proven large enough to sustain a focused brand with global reach.

    The Deeper Lesson

    The deeper lesson of Jack Tyler’s work is not only about what he creates but about how he built the authority to create it. He came up through performance, repair, and deep engagement with the saxophone community before any product existed. That foundation cannot be shortcut or scaled. Focus created identity, identity created trust, and trust created a community of saxophone players willing to follow him wherever the next design leads. The Boston Sax Shop thrives because it knows exactly what it is, and because the person at its center earned the right to define it.

  • When Marketing Rewrites History: The Problem With Using Legendary Players to Sell Mouthpieces

    When Marketing Rewrites History: The Problem With Using Legendary Players to Sell Mouthpieces

    This is not a hypothetical. Sponsored advertisements using black and white images of legendary saxophone players to sell mouthpieces those players never publicly played are circulating on social platforms right now. Assume, for the sake of argument, that every rights holder has been compensated and every contract is signed. Set aside the legal question entirely. The ethical problem remains, and it’s worth examining clearly.

    The scenario is familiar in spirit to anyone who follows saxophone marketing—striking images of legendary players deployed to imply a connection between their sounds and a product. The implication is unmistakable, but the problem is not legal. It’s historical, acoustical, and it’s a distortion of the record.

    Why This Matters for the Culture of the Instrument

    For saxophonists, equipment isn’t just gear; it’s biography and lineage. The mouthpiece choices of the instrument’s most influential players have been analyzed, measured, reverse-engineered, and mythologized. Those choices weren’t casual; they were integral to their voices. When a company uses the likeness of a legendary player to imply endorsement of a product that player never publicly touched, it does more than mislead consumers. It also misrepresents the acoustical lineage of some of the most influential players in modern saxophone history. It may confuse younger musicians, who may assume these mouthpieces were part of an artist’s signature sound. And it exploits reputations that the artists themselves can no longer clarify or correct regardless of what their estates have agreed to on their behalf.

    That last point deserves to sit for a moment. An estate can license an image. It cannot license an opinion the artist never expressed about a product that didn’t exist in their hands. There is a meaningful difference between the two, and serious players understand it instinctively.

    The Ethical Line

    There is a difference between inspired by and endorsed by. Between historical context and commercial appropriation. Between celebrating a legacy and leveraging it for sales. Reputable makers understand this distinction. They cite living artists who actually use their products. They document measurements, acoustical principles, and design choices. They don’t borrow the faces of legends to imply a lineage that never existed even if they have legal permission to borrow those faces.

    The saxophone community is unusually sensitive to authenticity because the instrument’s history is transmitted through sound, setup, and pedagogy. In a field where the relationship between the player, the reed, and the air column is already difficult to communicate accurately, precision about historical fact matters. When companies blur that record for commercial gain, even legally, they undermine the knowledge base that serious players rely on.

    The Bottom Line

    The great players of the saxophone’s modern era earned their sounds through decades of work, experimentation, and refinement. Their equipment choices are part of a legacy that is documented, studied, and respected by the community. To use their images to promote a product they never publicly played is not just misleading; it’s disrespectful to the history of the instrument and the musicians who shaped it. Legal permission from an estate does not resolve that. It only means the disrespect was negotiated.

    If the saxophone world is going to take acoustics, design, and artistic lineage seriously, then accuracy isn’t optional. It’s the baseline.

  • The Primacy of Response: Rethinking the Saxophonist in the Acoustic System

    The Primacy of Response: Rethinking the Saxophonist in the Acoustic System

    Years ago, in a conversation about equipment and sound development, Branford Marsalis told me that mouthpieces, reeds, and horns do not create a player’s sound. Players have to create their own sound.

    At the time the comment struck me as philosophical. In reality it is acoustical. When saxophonists discuss equipment, the conversation almost always centers on tone. Players describe mouthpieces, reeds, and ligatures using a vocabulary of color and texture such as darker, brighter, fuller, or more focused. Tone, however, is the final audible result. It is the sound wave that eventually reaches a listener’s ear. What the performer experiences first, and most intimately, is not tone but response.

    Response refers to the mechanical and tactile feedback that emerges between the musician and the instrument. It includes how quickly the reed begins vibrating, how much air pressure is required to sustain oscillation, how stable intervals feel, and how much resistance the player encounters. These cues form the physical experience of the instrument and strongly influence how a musician blows, voices, and ultimately shapes the sound.

    Within the player instrument system, tone is not the starting point. The player responds to the instrument, and the instrument responds in return. What emerges from that interaction is the sound we call tone.

    The Player and Instrument System

    Research in musical acoustics demonstrates that wind instruments do not operate independently of the performer. The sound emerges from a coupled system in which the vibrating reed interacts with the instrument’s air column while simultaneously responding to the player’s airflow, embouchure force, and the acoustic impedance of the vocal tract.

    Studies of wind instrument acoustics show that the resonances of the player’s vocal tract can interact with the impedance peaks of the instrument bore and influence pitch stability, timbre, and harmonic balance.¹ In certain registers players can even adjust the resonance of the vocal tract so that it reinforces or counteracts the instrument’s natural resonances.²

    The implications are significant. The musician is not merely operating the instrument. The musician becomes part of the acoustic system that produces the sound. As Arthur Benade emphasized in his work on musical acoustics, a wind instrument does not function as an isolated object. The vibrating air column, the reed, and the player together form a single interactive system.

    The Compensation Factor

    The human brain functions as a remarkably fast compensation engine. Every saxophonist carries an internal model of their desired tone that develops through listening, practice, and experience.

    As the instrument responds, the brain processes tactile and auditory feedback within milliseconds. When the response deviates from the intended sound, the player instinctively adjusts tongue position, throat shape, airflow, or lip pressure in order to bring pitch and timbre back into alignment.

    This adaptive behavior is consistent with psychoacoustic research showing that musicians routinely normalize perceived sound through motor compensation and perceptual calibration, a finding demonstrated in stringed instrument research and consistent with observed wind instrument behavior.³

    Why Equipment Changes Feel Like Tone Changes

    This feedback loop explains why even small equipment changes can feel significant.

    When a mouthpiece, reed, or ligature alters the instrument’s response by changing how easily the reed vibrates, how intervals settle, or how resistance is perceived, the player’s compensation system shifts accordingly.

    If a setup feels resistant the player may increase airflow or firm the embouchure to stabilize the vibration. These adjustments reshape the vocal tract and modify the forces acting on the reed. The harmonic structure of the sound can change as a result.

    The player therefore reacts not only to the acoustic sound radiating into the room but also to a stream of tactile and bone conducted feedback generated by the vibrating reed and mouthpiece.

    Research on reed bore interaction confirms that changes in upstream and downstream impedance influence the oscillation behavior of the reed and the stability of the resulting sound.⁴

    When a player hears a tonal difference after changing equipment the pathway is often indirect. The equipment alters response. The player adapts technique. Those adjustments produce the audible result. A well balanced setup reduces the amount of corrective work required to reach the player’s intended tone.

    Perception and Bone Conducted Sound

    Another factor shaping the player’s perception is bone conducted sound. When saxophonists play they do not hear the instrument only through airborne sound radiating into the room. Vibrations also travel through the teeth, jaw, and skull, contributing mechanical feedback to the inner ear.

    These bone conducted signals emphasize the tactile aspects of the instrument, including reed vibration and mouthpiece resonance. As a result, small changes in response or resistance may be perceived strongly by the player even when the radiated acoustic output heard by listeners remains largely unchanged. Because this feedback reaches the player through the jaw and skull rather than through the room, the sound perceived by the performer can differ meaningfully from the sound radiated to listeners.

    The Limits of Player Compensation

    Experienced players often notice that they sound remarkably like themselves across a wide range of setups. Their compensation mechanisms are highly developed and allow them to stabilize tone even when equipment changes. Many experienced saxophonists and knowledgeable industry professionals have observed that when skilled players test mouthpieces their tonal character often remains surprisingly consistent from piece to piece.

    A similar observation comes from the practical world of instrument retail. Jack Tyler of the Boston Sax Shop once described an experience involving the saxophonist Joel Frahm. Frahm had brought a large number of mouthpieces to the shop with the intention of selling them. Tyler suggested recording Frahm playing each piece so that buyers could hear the differences. After several recordings, however, Tyler stopped the session. Although the mouthpieces themselves were quite different, Frahm’s sound remained so consistent that the recordings revealed far less variation than expected. The player’s tonal identity dominated the acoustic differences between the mouthpieces.

    Experiences like this highlight how strongly a developed sound concept can stabilize a player’s tone across different setups.

    There is, however, a physical threshold beyond which the design of the instrument begins to constrain the player’s ability to compensate. When mouthpiece geometry changes substantially through shifts in baffle height, chamber volume, facing length, or tip opening, the impedance relationships between the reed and the air column shift in ways that alter the operating regime of the system. Fletcher and Rossing describe these behaviors as nonlinear oscillation regimes in reed instruments.⁵

    Beyond this point the instrument itself begins to influence the outcome more strongly. Consider exchanging the equipment associated with two very different alto players such as David Sanborn and Paul Desmond. Sanborn’s sound was associated with high baffle mouthpieces designed for strong air velocity, while Desmond favored small tip openings and large chamber mouthpieces with very low baffles. These designs create very different acoustic conditions. It would likely be difficult for either player to reproduce their signature sound on the other’s setup.

    Within a compensable range the player stabilizes the tone. Beyond that range the physics of the instrument begins to dominate.

    The Physical Limit of Compensation

    Even the most refined compensation has limits imposed by the acoustics of the instrument itself. One important constraint is the cutoff frequency of the woodwind tone hole lattice. Above this frequency the open tone holes cease to reflect acoustic energy efficiently back toward the mouthpiece. Instead the energy radiates outward and the impedance peaks that normally support reed oscillation become weaker.

    When mouthpiece geometry shifts the operating conditions of the reed toward stronger high frequency components, the coupling between the reed and the air column can become less stable. Players often perceive this as a loss of center or core in the sound because the instrument provides less reactive feedback through the standing wave system.

    Beyond this threshold the oscillation behavior of the system is governed primarily by the resonance structure of the instrument itself. As Fletcher and Rossing explain, the nonlinear reed oscillator ultimately responds to the resonances of the air column. The player’s vocal tract can shape the resulting spectrum, but it cannot redefine the resonances that the instrument supports.

    Rethinking the Equipment Narrative

    For the practicing musician, shifting attention from tone to response can reduce frustration and increase efficiency.

    Response can be understood through three practical dimensions. Inception describes the amount of energy required for the reed to begin vibrating. Connection refers to the stability with which the instrument transitions between notes. Resilience describes how well the system maintains stability across a wide dynamic range.

    When these factors are optimized the player can relax. A relaxed player maintains a more flexible vocal tract and steadier airflow. This in turn allows for a richer and more stable tone.

    Conclusion

    The sound of a saxophone does not originate solely in the instrument. It emerges from the interaction between the musician and the acoustic system they create together. Equipment influences that interaction by altering response, resistance, and stability. Players then adjust, often instinctively, until the sound aligns with their internal concept.

    Within a reasonable range of designs this ability to compensate allows experienced musicians to maintain a remarkably consistent tonal identity. When acoustic conditions shift far enough the instrument itself begins to guide the result.

    Musicians often believe they are chasing tone when they experiment with equipment. In practice they are chasing the feel of a response that allows that tone to exist.

    In the end, the equipment shapes the conditions of the system, but the player still has to create the sound. The musician steers the system, but the instrument defines the boundaries of the possible.

  • Authorship and Precision: The Design Philosophy of Mark Sepinuck

    Authorship and Precision: The Design Philosophy of Mark Sepinuck

    This essay is not about nostalgia. It is about authorship and a designer who refused to let accident masquerade as virtue. Mark Sepinuck represents a different kind of digital artisan, one who used modern manufacturing not to imitate the past but to reject it.

    For decades, the saxophone mouthpiece market has revolved around reverence for Otto Link’s and Meyer’s so‑called “good vintage years.” Entire businesses have been built on reproducing, approximating, refining, or lightly modifying those canonical geometries. Variability was accepted as charm, and inconsistency rationalized as personality. Players found themselves chasing rare outliers rather than relying on design intent. Against that backdrop, Sepinuck entered the landscape not as a historian but as a dissatisfied player.

    Like many serious players, he spent years acquiring vintage mouthpieces in search of something exceptional. What he found instead was inconsistency. Most pieces were mediocre at best, and nearly all required refacing to perform at their peak. The mythology surrounding them was strong, but the reliability was not. The search itself became the problem.

    Rather than continuing to hunt for the rare specimen, Sepinuck chose a different path. If vintage pieces could not be relied upon to play consistently, the solution was not better curation. It was authorship. He would design his own mouthpieces from the ground up, with clearly defined performance goals, and ensure that every example produced matched those goals exactly.

    The objective was never to create a single perfect mouthpiece. It was to create a family of original designs that were internally consistent, clearly differentiated, and predictable enough that players could choose a model based on musical need rather than luck.

    This commitment to originality is central to the identity of 10MFAN. Sepinuck refused to produce derivative interpretations of Link or Meyer geometries. In his view, endlessly iterating on familiar templates offered players little beyond branding. Fifty makers could produce their own version of a Meyer, but the player would still be navigating the same conceptual territory.

    So he declined to enter that territory at all. Instead, he focused on solving modern problems with modern designs. He developed a foundation piece that could serve as an all‑purpose reference and then expanded outward into models that intentionally moved warmer or brighter, broader or more focused. Each model was conceived as a distinct solution and not a tweak or revision.

    The development process reflects that philosophy. Early prototyping involved extensive hands‑on experimentation and physical modeling. Geometry was resolved through repeated iteration before any design was locked into digital form. Only once the internal structure matched the intended response did CNC enter the picture. At that stage, CNC was not a creative substitute. It was a preservation tool.

    Once a design was finished, CNC ensured that every rail, baffle, and chamber dimension reflected that finished idea precisely. The machine did not invent the mouthpiece; it protected it. The variability that once defined vintage production was replaced with repeatable authorship.

    The practical result was consistency without sterility. A player might not love every 10MFAN model, and they were not meant to. What was guaranteed was that each model performed exactly as designed. Selection became intentional rather than speculative.

    Sepinuck’s public presence mirrors his intensity as a designer. In online forums he is outspoken, highly engaged, and unapologetic in advocating for his work. This visibility is not incidental. It is an extension of authorship. He does not separate design from explanation, and he does not allow his products to circulate silently.

    In a market long dominated by inherited geometry and borrowed legitimacy, Sepinuck’s stance is unusually direct. If you are going to put your name on a mouthpiece, it should be your design.

    Modern manufacturing made this stance enforceable. CNC did not create his originality; it preserved it. That preservation—more than nostalgia—is what defines Mark Sepinuck’s contribution to the modern saxophone mouthpiece.

  • Are Higher Baffle Saxophone Mouthpieces Really Louder?

    Are Higher Baffle Saxophone Mouthpieces Really Louder?

    This essay has been revised with input from researchers in psychoacoustics and perceptual science. The author welcomes continued correction from experts in those fields.

    The belief that higher baffle saxophone mouthpieces are inherently “louder” remains one of the most persistent assumptions in the saxophone world. A player switches to a steep baffle, hits a note, and the horn seems to leap forward with explosive immediacy. The band reacts. The sound feels bigger and stronger. That sensation is real, and it deserves a precise explanation rather than dismissal. What the acoustics show is not that players are wrong, but that “louder” is often shorthand for “more spectrally concentrated, more directional, and more responsive.” Precision in language does not invalidate experience. It clarifies mechanism.

    What “High Baffle” Really Means

    In mouthpiece design, the baffle is the surface just behind the reed tip that directs airflow into the chamber. A higher baffle mouthpiece typically raises or steepens that surface near the tip, reduces effective chamber volume, increases initial air velocity, and shifts energy toward upper harmonics. A gentle rollover and an aggressive step baffle are not identical geometries, but both belong to the family of designs that emphasize higher partials. That spectral shift is central to the loudness question, because it changes how the ear interprets the sound, and not necessarily how much total acoustic power is being radiated.

    A Saxophone Is a Passive Resonator

    A saxophone does not amplify. It is a passive acoustic resonator. The player supplies air pressure, the reed converts that pressure into oscillation, and the bore shapes and radiates that oscillation into the room. If measured sound pressure level increases meaningfully, the additional energy must come from the player. A mouthpiece cannot create acoustic energy. It can only influence how efficiently your energy is converted and how it is distributed across the frequency spectrum. This is a foundational principle of acoustics.

    What Controlled Research Actually Shows

    Acoustical researchers have used artificial blowing machines for decades to remove the human variable. These systems deliver steady, repeatable mouth pressure, allowing mouthpiece geometry to be studied in isolation. Under fixed input conditions, total SPL differences between mouthpieces are generally modest, while spectral differences are more pronounced. Small increases in measured dB can occur between mouthpieces under identical blowing pressure, typically explained by differences in impedance matching and radiation efficiency.

    A higher baffle design may couple energy into the air column somewhat more efficiently at certain frequencies. But those total output differences are small. What changes far more dramatically is spectral balance, particularly the strength of upper harmonics, and the directional character of the radiated sound. The mouthpiece reshapes the spectrum well before it meaningfully increases total acoustic power.

    The Perceptual Science of Brightness and Projection

    Higher baffle designs reduce chamber volume and accelerate airflow near the reed tip, altering the reed and bore feedback relationship and strengthening upper harmonics. The result is a shift in the sound’s spectral centroid, the acoustic correlate of perceived brightness, toward higher frequencies. This is what listeners and players perceive as brightness or edge.

    Human hearing is not uniformly sensitive across frequencies. The equal-loudness contours first described by Fletcher and Munson in 1933, and refined extensively since, show that the ear is dramatically more sensitive in the 2 to 5 kHz range than at lower frequencies. A sound with more energy concentrated in that band will be perceived as substantially louder than its measured SPL alone would predict. Higher baffle designs tend to concentrate spectral energy in or near that window.

    This is not a perceptual illusion. It is the auditory system responding accurately to a genuine acoustic change, a redistribution of spectral energy into frequencies it is most sensitive to. Players are not mishearing their instruments. They are hearing exactly what is there.

    Increased spectral brightness also affects perceived projection. Higher frequencies radiate more directionally, so the sound appears to carry farther across a room or bandstand even when total radiated power is nearly the same. Projection describes the spatial distribution of energy, not an increase in total energy.

    The Player Is the Missing Variable

    Higher baffle mouthpieces also change how the instrument responds. They often feel faster, less resistant, and more immediate. That sensation of edge and immediacy encourages players to lean in, which increases blowing pressure and reed oscillation amplitude. Now the SPL genuinely rises, and the geometry did not create that increase. It changed how the player drove the system.

    In laboratory conditions, where input pressure is fixed and the human variable is removed, those dramatic SPL jumps do not appear. When a human player is involved, behavior changes along with output. The mouthpiece reshaped the driving conditions, not the fundamental acoustic capacity of the instrument.

    History Makes the Point

    The players who preceded the modern high baffle era did not sound small. Dexter Gordon filled concert halls with a sound that was enormous, resonant, and unmistakably powerful, long before aggressive contemporary baffle geometries existed. That is not a controlled comparison, and it should not be treated as one. What it illustrates is that projection at the highest level has been achieved across a wide range of mouthpiece geometries, which is consistent with what the controlled research shows: that spectral redistribution and player input, not baffle height alone, are the primary drivers of perceived loudness and carrying power. The acoustics explain the legend. The legend does not prove the acoustics.

    The Verdict

    Higher baffle saxophone mouthpieces can produce small increases in measured decibels under fixed blowing pressure, likely due to differences in impedance matching and radiation efficiency. But the dramatic loudness players describe is primarily the result of spectral redistribution into frequencies the ear is most sensitive to, increased directional radiation, faster transient response, and, in real playing conditions, increased player input.

    These mouthpieces are not amplifiers. They are redistributors of the energy you already supply, and they shift that energy into precisely the frequencies your ear and your audience’s ears are most sensitive to. That is a real and meaningful acoustic advantage. Players who choose higher baffle pieces for projection, presence, and carrying power are making acoustically rational decisions. The perceptual science supports them.

    Understanding this does not diminish higher baffle designs. It clarifies them. It shifts the conversation from chasing mythical volume to mastering spectral control, projection, and input efficiency. The sensation players describe is accurate. The mechanism behind it is simply more interesting than “louder.”
