Well, my father was a musician, and I felt this would be a good way to relate to him, and he actually worked with me on it. And you could feed in music like, you could feed in, let's say, mozart or Chopin, and it would figure out how they created melodies and then write melodies in the same style. So you could actually tell this is Mozart, this is Chopin. It wasn't as good, but it's the first time that that had been done.
