Music of the Spheres.

Composer Terry Riley has a new collaborator, the Solar System. Space probes pick up the varying magnetic waves that surround planets and moons. These waves can be converted into sounds, sounds which Riley is drawing from for his newer compositions. Speaking of his inspiration the composer reported that in listening to patterns produced by the magnetic field around Ganymede, a moon of Jupiter, It sounded to me like a voice saying, 'beebopterismo,' so that's the starting point for one of the movements. The universe has spoken.
