Thanks, Chen. This is interesting material. It shows very nicely the unique
musical and acoustical characteristics of this highly sophisticated flute.
By the way, the spectral features are not so much a question of register,
but depend mostly on the applied blowing technique of the artist. This
becomes obvious in the Eb of the first line and the F-Eb-F in the second
As to the question of multiple pitches in one sound, I do not hear any. I
hear always one F0 pitch, and sometimes additional high-frequency
components. I tried to find out if these were caused by single partials or
by partial combinations. This turned out to be impossible, though, because
of the (non-octave-related !!) Cent scaling on the y-axis of the sonograms.
Could you perhaps add here a frequency scale in octaves (500, 1000, 2000 Hz,
etc.)? After that I would try again.
