I sounded like a drunk Jazz musician. (Not that drunk Jazz players are necessarily a bad thing.) Is there an ABBA mode? I actually once noticed that melodies of popular tunes tend to hover around the chord keys. The duration and probability of a given note favors chord keys. I built a Compose-A-Tron based on this pattern, and it mostly worked, but probably wouldn't generate any #1 hits. (Although, it could be improved with tweaking; but so could ordinary draft "on paper" compositions.)
