Re: Shortening down a barrel

I have some concerns about the statement that the primary characteristics of the barrel would remain the same.

On a typical 65 mm barrel, the upper tenon socket is about 17 mm, and the lower socket is approx. 19 mm. That leaves about 29 mm of actual "bore" in the mouthpiece. If you reduce the barrel down to 55.5, you are effectively reducing the bore from 29 mm to 21.5 mm, or a reduction of over 26%.

That in itself has got to change to response, as less of the total clarinet bore is hard rubber. Also, the bore of the barrel would have to be perfectly cylindrical for there not to be a big change in how it responds or tunes. It would also make a difference if you shortened the barrel from the top down, or the bottom up.

It would certainly make an interesting experiment!
