Why it’s interesting
Lejaren Hiller and Leonard Isaacson used the ILLIAC computer in 1956 to generate musical material for a string quartet. The work is a landmark of early computer-assisted composition, built from explicit rules and musical experiments.
Decades before today's generative AI, people were already giving musical constraints to a computer and asking human performers to turn the output into sound.
How to try it
Read the University of Illinois museum entry for the experiments, score, and premiere context, then find a recording to hear how the rule-based sections differ from one another.
Use the official page or demonstration as the current reference. Do not assume that a staged installation, limited experiment, account-gated demo, subscription feature, or physical product is available everywhere.
