Kepler's Music of the SpheresKepler refers to Pythagoras' music of the spheres in the 12th chapter of his Mysterium Cosmographicum. See (Koestler, 1960, p. 51). In Kepler's version, each planet plays a wailing sound, like a trombone. The pitch of each planet's trombone was to be proportional to the angular velocity of the planet.
In this site we develop all the basic concepts, and a strategy to print out a table of pitch data for each planet, based on the integration of an ordinary differential equation (ODE) equivalent to Kepler's Second Law.
