Common music : Automatous monk
“Automatous Monk is an algorithmic music composition program that uses cellular automata to generate musical pieces.” It is written in Java and you can find it on sourceforge somewhere. You can also simply enjoy its compositions by downloading creative commons licensed soundfiles from the Automatous monk personal website.
“Monk has just finished composing his first punk rock/hard bop work, The Well-Tempered Cellular Automaton, consisting of preludes and fugues in all 24 major and minor keys.
Automatous Monk considers this to be his best work yet. He describes it as being, “about 9/10 hard bop, and 1/10 80s hard-core; maybe ‘insistent’ would be the best word for this new record. Or, ‘relentless’, maybe”.”
