Notes are the written pitch.
Frequencies are the sounding frequency, for Bb saxophone.
Unless otherwise stated, the impedance spectrum is for a Bb saxophone.


Impedance spectrum of a Bb saxophone measured using fingering for the multiphonic D#4, F5, C#6 and E#6 .

Here, the D#4 may be considered as produced by a variant of the E4 fingering, with cross fingering to make it flatter. The F5 may be considered as a peculiar perturbation fingering for G5, with cross fingering and a poorly placed register key. It is difficult to explain the higher notes by such simplistic means: once we are at or above the cut-off frequency, the whole bore is involved.
