This is something I've been think ing about for a while and would like some opinions on its feasibility. I suppose I should start with some background: On saxophone, among other wind instruments, altissimo range (notes above normal range) are reached by either by playing on a different partial than a fingering is supposed to bring out or forcing that partial through special fingerings. For reference, the overtone gammut from Bb: Bb1, Bb2, F2, Bb3, D3, F3, Ab3, etc. I know it's probably not possible pizz, but with the bow it's fairly easy to bring out the octave and octave and a fifth partials, so more should be possible with practice, no? I think if one were to gain enough control over the overtone series they would be able to make some cool music, not to mention how much easier some intervals would be.
