Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
With one hole open, the filtering effect of the downstream holes is noticeable at frequencies above 2 kHz. The first seven minima can be played, but usually flute players only play the first, for which the higher minima aid the production of harmonics. For another comparison of the filtering effect of one tone hole, compare C4 on this flute with C4 of a B foot flute.
