This document introduces programmable music, describing how a programmer can create music using Clojure and Super Collider. It explains that Clojure is a Lisp implementation that runs on the Java Virtual Machine and has a similar syntax to other Lisps using s-expressions. Sample code is provided to define and call a simple function in Clojure. The document then discusses how the open source Super Collider audio environment can be used with Clojure for frequency modulation synthesis, sampling, and sequencing to programmatically generate music.
