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 A6 with C7 .This multiphonic operates at the 7th peak (3rd major peak) and the 8th peak. By adjusting a strong impedance peak of the vocal tract (see this page for an explanation and some interesting results), the player can obtain a trill alternating between A6 and C7, perfect for playing the blues in written G.
