Um, I don't understand the point you are making here Andy.

Are you alluding to the fact that Mozart didn't make his BPM harmonic to the 
key? That's because he didn't have access to Graham's BPM calculator!

I suspect Graham means 'equal temperament' - which incidentally wasn't common 
practice until the development of the Pianoforte. Suffice it to say that 
Bach's 'well tempered clavier' wasn't 'equal tempered' - this accounts for 
why many classical composers favoured keys like Eb Major - not only does it 
fall under the fingers nicely, it also would have sounded considerably 
sweeter than, say F# Major.

Apos to anyone who is wondering what this has to do with Linux. It's just one 
of my Hobby-horses and comes synchronicitously with a thread on another 
completely unrelated mailing list. Whoopee!
