[Slashdot] - Musicians Algorithmically Generate Every Possible Melody, Release Them To Public Domain

[Admin]

Two programmer-musicians wrote every possible MIDI melody in existence to a hard drive, copyrighted the whole thing, and then released it all to the public in an attempt to stop musicians from getting sued. From a report: Programmer, musician, and copyright attorney Damien Riehl, along with fellow musician/programmer Noah Rubin, sought to stop copyright lawsuits that they believe stifle the creative freedom of artists. Often in copyright cases for song melodies, if the artist being sued for infringement could have possibly had access to the music they're accused of copying -- even if it was something they listened to once -- they can be accused of "subconsciously" infringing on the original content. One of the most notorious examples of this is Tom Petty's claim that Sam Smith's "Stay With Me" sounded too close to Petty's "I Won't Back Down." Smith eventually had to give Petty co-writing credits on his own chart-topping song, which entitled Petty to royalties. Defending a case like that in court can cost millions of dollars in legal fees, and the outcome is never assured. Riehl and Rubin hope that by releasing the melodies publicly, they'll prevent a lot of these cases from standing a chance in court. In a recent talk about the project, Riehl explained that to get their melody database, they algorithmically determined every melody contained within a single octave. 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. Once a work is committed to a tangible format, it's considered copyrighted. And in MIDI format, notes are just numbers.
