Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
This fingering is comparable to that for D4 except for the open register hole. The register hole weakens and detunes the first resonance. We can also consider that it creates a pressure node (or flow antinode) at the midpoint of the pipe, and thus allows D5 but not D4. Compared with the D4 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 |
