MS#156. Kepler's Music --- a Computer Simulation, 2019 Subjects: Visual Math, Visual Music Abstract: This article is a supplement to my presentation at the conference, The Harmony of the World at the Kepler Archives, Saint Petersburg, Russia, 21-23 June, 2019. It is a report of joint work with Pablo Viotti. We presented stereo- audio and video recordings of our computer simulation of Kepler's planetary music, as described in Book V of his Harmonice mundi. The video synchronizes the combined sounds of the planets with a visual display of the planetary disks, as seen by angels watching from a window in the Sun, similar to the view from the moon described in Kepler's Somnium: the dream, or posthumous work on lunar astronomy.Mathematical theories of information transmission may be applied to this channel.
