Wolfram Tones

This is a cool find. Wolfram, the makers of the excellent do-everything program Mathematica, have a whole mess of sites devoted to math and physics extensions of Stephen Wolfram’s book A New Kind Of Science. One of the sites is called Tones, and generates aleatoric music based upon algorithms for same described in the book. According to the FAQ:
_
WolframTones works by taking simple programs from Wolfram’s computational universe, and using music theory and Mathematica algorithms to render them as music. Each program in effect defines a virtual world, with its own special story–and WolframTones captures it as a musical composition.

It takes some fooling about to come up with good stuff, and the simpler forms of music (e.g. Dance) generally sound better than the more complex forms (e.g. Classical.) But once you come up with something you like, you can download it as a ringtone, save it, email it to a friend, whatever. It’s a really cool application of what Mathematica is capable of, and well worth a look.
