Musical Theory

An old friend recently wrote a guide to music theory called Western Music from First Principles. It's a great summary that goes from the underlying physics of the notes and pitches through basic tones for compositions, up through modern scales and how they work.

Neat stuff. I play a couple of instruments and hadn't known a lot of this. It's worth a read.

That same guy...

In case you liked the previously-linked essay on music theory, here is the same fellow playing a composition of his own on piano. arbus at least seemed vaguely interested, so maybe other people are too :-)
