Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering is comparable to that for D#4 except for the open register hole. This creates a pressure node (or flow antinode) at the midpoint of the pipe, and thus allows D#5 but not D#4. Compared with the D#4 impedance spectrum, the low frequency minima are less deep, and at considerably higher frequency.
may suggest other fingerings for this note.| Acoustic measurements are available for these flutes - modern B, modern C, classical C, classical D, classical flared, baroque Sound clips are available for modern B, classical flared and baroque |
