Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
The flutist uses the same fingering for A4 and A5, but changes the speed, length and shape of the jet. The first four minima can be played. These minima support harmonics in A4. In A5, only the second and fourth minima are important. (Inaudible traces of the lower note are visible in the spectrum for A5 which has tiny bumps at harmonics of A4.)

Fingering Acoustic schematic Non-specialist introduction
to acoustic impedance |
The rather small differences in the impedance spectrum, seen well above the cut-off frequency, have negligible difference in the playing regime, and the differences between the sound spectra are largely due to the variation produced by recording live musicians under comfortable conditions.
