 Re: Sharp on high notes... flat on low F and low E

This may be theoretically true, but is this absolutely true in real life?

In my understanding, which may of course be flawed, at least some overtones of a note played on a piano are mathematically out of tune with the mathematical interval, hence producing beat frequencies with the sam note which is the fundamental of another string. This is one of the reasons for 'stretching' the octaves of a piano, in order to slow down those beat frequencies and make them less conspicuous. As far as I know, these anomalies are caused by the inherent imperfections of the string itself, especially the stiffness where it crosses the bridge, some compensation being made by where the windings of bass strings finish - short of the bridges.

Seeing there are equivalent imperfections in the air column in wind instruments, I would expect similar anomalies in them. Is not the pitch of each harmonic dependent on the length of the air column, and does not that EFFECTIVE length of this column extend beyond the first open tone hole, and does not the distance of this extension depend on the frequency of the particular harmonic?

And is it not true that the taper in a sax/oboe/bassoon bore is adjusted to get those harmonics in tune? are there not anomalies in the effective bore diameter in clarinets too, on account of the tone holes.

Perhaps there is somebody here more enlightened than myself?
