Re: [harmonic_entropy] Digest Number 144

Manuel, Paul, etc. Thanks, I may be contacting you personally if I can't
find the relevant posts or understand them.

I've been experimenting with the Tonicity function (in an old paper I
could lay my hands on easily last weekend) and have some graphics, one
of which I will try to upload to the file area.

The parameters are these: S=.01, T=1200 (tet), N*D <=10000 and N/D
reduced to one octave, the colors are arbitrary and the scale factors
were chosen to fit on my rather small screen. The equation is
(1/(sqr(2*pi)*sqr(N*D)*S))*exp(-(((log(N/D)-NT)^2)/2*S^2 )) where
N=Num,D=Denom and NT is log of the nearest tempered note to N/D.
Note the peak at 3/2; the bottom line is cents marked every semitone.

Paul, it seems you never replied to this? I'd love to read
any feedback you might have on it.
