Evidence-based inquiry into sound and culture
Category: Jazzocrat’s Player-Centered Research
Essays examining the saxophone from the player’s perspective, drawing on acoustics, physiology, and psychophysics to understand how the instrument, the body, and the mind interact. Topics include embouchure mechanics, vocal tract function, mouthpiece intake, reed response, and the perceptual experience of playing. This research is grounded in collaboration with acousticians and physicians.

Every saxophonist has noticed that changing a mouthpiece changes more than the sound. It changes how the reed feels, how it responds, and how hard the instrument asks you to work. Most players attribute this to tip opening or chamber geometry, and those things matter. But the facing curve, the shape of the lay against…

For decades I believed my idealized tonal concept was a myth. Not a destination I had not yet reached, but something structurally unreachable, a mythical sound that existed only in my mind and would stay there. I understood the acoustics. I had studied under one of the finest mouthpiece craftsman of his generation. I had…

In a previous trial documented on this site, my colleague and I compared five clarinet ligatures under blinded conditions and found that four were indistinguishable by sound or feel. The fifth, the Ishimori Kodama II, stood out consistently enough that I advanced a hypothesis about its wooden reed plate as a proprioceptive mechanism. This follow-up…

A blinded two session clarinet ligature trial comparing five designs found no detectable tonal differences between four conventional ligatures, while one structurally unusual design, the Ishimori Kodama II, produced a consistent and reproducible proprioceptive sensation. This post documents the methodology, results, and a discussion of what the Kodama’s wooden reed plate may reveal about mechanical…

The saxophone produces sound through an interactive system that includes the player. This essay examines why response, not tone, is the primary variable a saxophonist controls, and what acoustic research reveals about that relationship.

Mark Sepinuck of 10MFAN rejected the saxophone mouthpiece market’s dependence on vintage geometry and built an original line of CNC-precision designs. This essay examines his philosophy of authorship.

Higher baffle saxophone mouthpieces feel louder because they shift spectral energy into the frequencies the ear is most sensitive to, not because they increase total acoustic output. Players choosing these mouthpieces for projection and presence are making acoustically rational decisions. Here is what the perceptual science shows.

A saxophone ligature has one job: to secure the reed. This essay explains the mechanical role of the ligature as plainly as possible and addresses why so much confusion persists around what is, at its core, a very simple device.

The terms saxophonists use to describe mouthpieces, free blowing, resistant, spread, focused, reflect real physical sensations rooted in geometry. This essay examines the architectural principles behind them.

This two part essay examines the gap between a saxophone mouthpiece’s acoustic performance and the player’s physical experience, comparing two identical geometries made from different materials.
