Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering is comparable to that for F4 except for the use of one of the G# keys and the LH thumb key as register holes. Comparing this with the F4 impedance spectrum, we see that the fifth minimum is a little deeper. The first minimum plays ~C5 and the second ~B5 but, because it is a cross fingering for these notes, their timbres are darker. Combinations of these three notes may be played simultaneously as multiphonics. Compare the impedance spectrum with that for C7 on a flute with a B foot, whose working minimum is several dB deeper. The enhanced ease of playing C7 softly is an advantage of the B foot.
