something Helmholtz and Partch left out

Thanks for the kind words. And say - what's wrong
with Helmholtz and Partch that they dont mention the
tuning list in their books?

I bought Bill's book, too! It came in two days from Amazon.com!

I've sent them *dozens* of e-mails and they haven't replied ... probably
some server glitch :-). While I've got the expert here, I've been trying to
duplicate your dissonance curves in Derive. I noticed that the two codes
(BASIC and MATLAB) differ in the strengths of the partials, with the BASIC
code using amplitudes that diminish by a factor of 0.88 each time and the
MATLAB code using amplitudes of 1.0 for all the partials. And neither of the
codes is structured the same way as the equations, although they are
equivalent except for some scaling factors. My main question is, "Where did
the 0.88 factor come from?" Is it meant to emulate some real musical
instrument, or did you pick it because it generated reasonable curves and
"interesting" sounds?
