I got my hands on a beautiful Yamaha SEV Master KF - same model as John Bruce Yeh used for a while, two tone silver/gold, E/F correction key, the works. I'd really like to keep it, but...
The twelfths are quite narrow on this clarinet. The whole chalumeau is about 15 cents sharper than the clarion. (Eg C4 is 17 cents sharper, G5 2 cents sharper.)
Nothing I can think of would cause that sort of behavior. Does anybody know if this something that has a fixable cause?
A more specific question would be: is this something that a mouthpiece/barrel change can fix, and is there any material out there on the effects for different combinations? I did search for measurements on the effect of those on tuning - eg, between a BD5 and a M15 with reeds blah we have these deltas in cents - but found nothing.
