Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering is comparable to that for G4 except for the use of one of the trill keys and the LH 2nd finger key as register holes. The register holes create a pressure node (or flow antinode) about three quarters of the way along the pipe, and thus allows B6 but not B4, B5, or F#6. Comparing this with the B4 impedance spectrum, we see that the fifth minimum is a little deeper. The third and fourth are shallower and unplayable. The first minimum plays ~D5 and the second ~C#6 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.
