[math-fun] Ascending tones

The notes are shown and explained in Godel-Escher-Bach. Just ask Scott Kim to play them for you, the next time Scott and a baby grand piano happen to be nearby. --Ed Pegg Jr, www.mathpuzzle.com

I don't know. But I once saw it combined in a neat way with one of Escher's infinitely ascending staircases. As one watched a ball bouncing perennially upwards, one heard the ever-rising tone! I'd love to see and hear it again.
