Francis,
Thanks for the ref to Arthur Benade's book. I've just bought it, and first
indications are that it is excellent!

It's really much more like the effect caused by a tiny irregularity in a
tooth. It seems massively more important than it actually is.
There's absolutely no possibility of "theoretically perfect" behaviour in
a woodwind bore, so consequently these insignificant irregularities cannot
possibly disturb such perfection.
Practically speaking (unless one is unbelievably expert) the factors
influencing sound waves in an NSP bore are a good mixture of the laws of
Physics and Sod's Law. In varying proportions, obviously.
I don't think I've seen Arthur Benade's Fundamentals of Musical Acoustics
mentioned in this forum. I certainly can't claim to know it well, or to
understand most of it. But I think it is one of the best regarded
textbooks on musical acoustics written by a first class scientist who also
enjoyed making musical instruments (especially wind) when he wasn't busy
with the day job.
I'm mentioning this here because it's a book I turn to in curiosity when
the behaviour of woodwinds is in question.
