Subj: Re: [kl] Tone hole diameter

Enlarging the holes of an instrument doesn't only affect the pitch. Maybe
somebody, long, long ago, tried it with an A clarinet and found the
tone
was adversely affected - IHHO.
Furthermore, A clarinets are traditionally played with what must be
sub-optimal mouthpieces, which may well create problems which have not
been thoroughly addressed.
