But is there nothing new under the sun? Is it possible that any music you write is always going to be a copy of something else, because everything is already written? Let’s stick some factorials on this question and find out.
Correction: I screwed up on the math for the number I mention at 6:33, defining the number of possibilities for a 3-note sequence. The number should be 397, not 66. My apologies!
Warning: There’s a lot of math here. If you’d rather skip the way we figured out how to get the answers and get to the answers themselves, skip ahead to 6:20.
