You are incorrect, but that's OK. A shorter than normal barrel (whatever
that is or might be) raises pitch most on the very short tube length notes
such as second ledger line high C and B below it, the throat tones of first
space F#, open G, G#, A and Bb. As more fingers are closed and the tube gets
longer, each lengthier note is sharpened progressively less and less. When
one uses a short 64 mm barrel on an instrument that was originally designed
to use a barrel length of around 66 or 67 mm, the tuning of the instrument
is drawn very much out of tune with itself.

Besides barrel length effecting tuning, the mouthpiece can have a great
influence on both specific tuning and overall tuning. I believe Clark Fobes
and possibly Thom Ridenour have articles that address how all of these
things fit together.

Maybe Mark Charette, Mark are you there? can point you to a web address that
will get you to thinking about this on more encompassing terms.
