Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering may be considered as that for F4/5, but with a register hole. Simultaneously, it could be considered as the trill fingering for D5 (C5 to D5 / C#5 to D5), but with considerable cross fingering to lower its pitch to ~C5. The first two minima correspond to these pitches. The third and fifth minima can also be played.
For this situation to apply, the frequencies of the notes have to be such that the effect of the inertia of the air in the open tone hole is large enough to allow some transmission past the hole, but small enough to produce some reflection. For low-pitched notes, the tone hole is usually small.
You can hear the multiphonic C5 with
