Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
The flutist uses the same fingering for C5 and C6, but changes the speed, length and shape of the jet. The first three minima can be played.

Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering has a reasonably strong impedance minimum for C5, but it is not well supported by minima at harmonics of this fundamental. The result is a soft 'covered' timbre. The fingering may be considered as that for C#5, but with cross fingering, which both lowers the pitch and detunes the higher resonances. It is, of course, the standard fingering for D6, in which the open key operates as a register hole.
