Musicians Algorithmically Generate Every Possible Melody, Release Them to Public Domain.

To determine the finite nature of melodies, Riehl and Rubin developed an algorithm that recorded every possible 8-note, 12-beat melody combo. This used the same basic tactic some hackers use to guess passwords: Churning through every possible combination of notes until none remained. Riehl says this algorithm works at a rate of 300,000 melodies per second.
