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 D4 and D#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 E5.

This note is, acoustically at least, a cross fingering: there is a key closed below the first open key, as the schematic inset shows. Because of the large size of the tone holes, cross fingerings have little effect at low frequency.

For general comments about the first register, see A#3. Compare with the impedance spectrum for a tenor sax on written E4: same fingering but sounding one octave lower.
