Low · A3
Reed and bore response, held note.
Instrument study · 01
Alto sax, from the reed out.
Starting with the horn itself: a pressure-driven reed, a widening bore, and the player’s breath controls. No tune or melody is involved yet.
Long-tone checks
Isolated concert-pitch A notes across three registers. Compare the same middle A with vibrato added.
Middle · A4
Straight-tone control, held note.
Upper · A5
Higher effective bore setting.
Middle · A4 + vibrato
Same note and model; player vibrato control enabled.
What is being modeled
The sound is generated by the coupled reed and bore—not assembled from a bank of preset harmonics.
ReedMass, stiffness, damping, changing aperture, and nonlinear airflow.
BoreEight widening waveguide sections with impedance scattering and propagation delay.
Bell / openingFrequency-dependent reflection and radiation at the open end.
Player controlsBreath-pressure attack and release, subtle airflow variation, optional vibrato.
