Overtone is a SuperCollider client written in Clojure. SuperCollider itself has a much larger library of useful code relevant to music theory.

The guy who wrote Overtone did so while he was learning music, but he isn't actually a composer. SuperCollider was developed mostly by academic musicians with a deep knowledge of experimental and traditional computer music practice. So it and the Quarks (packages) community have a wealth of code to explore.
