Illiac Suite (later retitled String Quartet No. 4)[1] is a 1957 composition for string quartet which is generally agreed to be the first score composed by an electronic computer.[2] Lejaren Hiller, in collaboration with Leonard Isaacson, programmed the ILLIAC I computer at the University of Illinois at Urbana-Champaign (where both composers were professors) to generate compositional material for his String Quartet No. 4.

The piece consists of four movements, corresponding to four experiments: the first is about the generation of cantus firmi, the second generates four-voice segments with various rules, the third deals with rhythm, dynamics and playing instructions, and the fourth with various models and probabilities for generative grammars or Markov chains.[3]
