In roughly 360BC, Plato shared his dialogue Timaeus, in which he imagined the universe as a geocentric system, including a concept called Music of the Spheres where each planet had its own sonic tone based on its unique orbital revolution. The entire system was divided into an octave, a fifth, a fourth, and tone, and as all the planets revolved around the Earth, the solar system would comprise a perfect musical score.
