Incoherent burblings

I now have a mathematical introduction to matrices at
http://www.cix.co.uk/~gbreed/matritut.htm

The site at www.treasure-troves.com is down whenever I try it. Is anyone
else having problems?

Another thing I don't think I've mentioned before. There's a book I saw
in an advert a while back, and have now tracked down again, called "Modern
Computer Algebra" by Gathen and Gerhard. Here's a link:

http://www-math.uni-paderborn.de/mca/

As well as looking generally interesting, it purportedly covers "a wide
variety of applications (including in chemistry, coding theory,
cryptography, and the design of calendars and musical scales)".

The website suggests the stuff on musical scales is a complex way of
getting 5-limit 12-equal out. Has anybody actually seen the book, and so
can comment on it?

I'm not sure about calling Dan Stearns' 7+3 JI scale "Graham's scale". I
never proposed a JI mapping.

As regards the 1812 Overture and the cannon. Yes, this may be a reason
why it's performed so often. But why complain? How about writing
microtonal pieces that also involve cannons, or other pieces of military
hardware? Then they might get to be as popular!

Right, I'll go back to slee^H^H^H^Hwork now.

The interpretation of a neutral third as 11:9, a neutral seventh as 11:6,
and a half-sharp fourth as 11:8, as well as the vanishing of the 243:242, is
equivalent to using your scale and "believing in 11-limit harmony", is it
not?
