The goal: to copyright every single combo in order to give it to the public so musicians and artists can use melodies without worrying about copyright issues down the line.
The algorithm created by the two programmer-musicians can put together every single 8-note, 12-beat melody combo. According to Riehl, the algorithm can generate 300,000 melodies per second. In order for these melodies to be copyrighted, they must be created as a work. So, the algorithm outputs MIDI files of the melodies to a hard drive.
