No, Jacky, I'm in fact referring to the Information Theory definition of
entropy, which minus the sum over a bunch of possibilities of p*log(p),
where p is the probability of the corresponding possibility. In the case of
Harmonic Entropy, the possibilities are the ratios in the Farey series or
whatever series is being used as the total set of ratios.

None taken. See http://www.ixpres.com/interval/td/entropy.htm for a
collection of my early posts to the Tuning List on the subject.
