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

This is the sixth note in the second register. It differs from G4 (the corresponding note in the first register) in that it uses a register hole. This causes a leak in the bore that weakens the first impedance peak, but has little affect on higher peaks – see register hole for an explanation, and compare with G4, whose impedance spectrum is almost identical except for the first peak. Above about 1 kHz, the third peak is weakened and the rest of the curve is irregular: see the discussion in cut-off frequency.

Compare with the impedance spectrum for a tenor sax on written G5: same fingering but sounding one octave lower.
