Subj: Re: [kl] Benade Clarinet Mouthpiece Overblowing at the Octave?

Dee, I think the statement you made is precisely the issue being
questioned. While a clarinet with a clarinet mouthpiece certainly
overblows a 12th as we all know, there is hard evidence in terms of
empirical experimentation suggesting that a clarinet with some other
form air excitation capability (i.e., an oboe reed stuck in a cork in
place of a traditional mouthpiece) will NOT overblow a 12th.

I don't know why this phenomenon occurs. I would like very much to
understand why it happens. But that it does happen contrasts negatively
with your statement reproduced below. There has to be something beyond
the geometry of the bore that produces the phenomenon described. Or, to
say it another way, there is something in the use of an oboe reed (or a
basson reed and perhaps other mechanisms) attached per the above
description, that negates the bore geometry and the influence it
normally has on the magnitude of the instrument's overblow characteristics.
