Here’s the passage from The Einstein Factor that I mentioned the other day.

Between 1965 and 1969, I picked up the habit of tinkering on the piano with a tape recorder running. I had no musical training, and probably even less natural talent. Yet I found that if I tinkered without inhibition or self-consciousness, simply pretending or acting as if I were playing a real piece, some portions of the ensuing cacophony would actually resemble music. As I listened to these tapes, I found that I tended to screen out the discordant parts while the pleasing parts stuck in my head. This feedback loop reinforced in me the behavior of producing pleasing sounds. Within a short time, the tendency to emit discordant noise had entirely dropped out of my consciousness, and I found myself playing lengthy, highly musical pieces quite spontaneously.

I’ll get back to this.
