RE: 19TET trumpet

Kami asked,

>How do you calculate the frets' positions?

John Starrett, who built Neil Haverstick's 19-tone guitar and is working on
a 22-tone guitar for me (how's it going, John?), recently posted to the
effect that the naive method is correct. That is, if the scale length is s,
and you want x-tone equal temperament, the nth fret is placed at a distance
of s/(2^(n/x)) from the bridge. After this is done, the usual process of
adjusting the intonation of the octave by moving the bridge saddles should
give good results across the fingerboard. I hope he's right!

Hear! Hear! I found John Chalmer's encyclopoedic overview of tuning
extremely valuable. It would be nice to have access to that talk again eg.
if it was produced on CD-ROM. (Hint, hint, Larry). Regretably, I was
unable to attend Bill's talk.
