This is a fascinating read. I couldn’t help but substitute “poetry” for “music” while reading it. A couple of excerpts:
Cope has been writing software to help him compose music for 30 years, and he long ago reached the point where most people can’t tell the difference between real Bach and the Bach-like compositions his computer can produce. Audiences have been moved to tears by melodies created by algorithms. And yet, it’s not exactly that Cope has created a computer than can write music like a human. The way he sees it, it’s that humans compose like computers.
…human composers draw on a huge amount of data when they sit down to write a piece of music. “We don’t start with a blank slate,” [Cope] said. “In fact, what we do in our brains is take all the music we’ve heard in our life, segregate out what we don’t like, and try to replicate [the music we like] while making it our own.” What separates great composers from the rest of us, he says, is the ability to accurately compile that database, remember it, and manipulate it into new patterns.
