Impedance spectrum of a Bb saxophone measured using fingering for G#5.

Note how similar this spectrum is to that for C#4. (Of course, the clarinet overblows a 12th.) The only substantial difference is the reduction and detuning of the first peak. The purpose of the speaker key is just that: to weaken and to detune the fundamental resonance so that the instrument will not 'drop down' to the lower register. See register hole for details.

For a general discussion of the clarino register, see the description on B4.
