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

At frequencies below about 1 kHz, this curve looks rather like that for F4 and F#4, but raised in frequency. At higher frequencies, however, the situation is complicated by the cut-off frequency. Here, the 1 kHz cutoff is also weakening the third peak. The first peak can be reduced in magnitude and shifted in frequency using a register hole (operated by the octave key): see G5.

For general comments about the first register, see A#3. Compare with the impedance spectrum for a soprano sax on written G4: same fingering but sounding one octave higher.
