Both Pythagoras and Johannes Kepler believed that the planets move in harmony. Pythagoras is associated with the idea of a cosmic harmony or music of the spheres, where the movements of celestial bodies are seen as contributing to a harmonious whole. Johannes Kepler, while he developed a more scientific understanding of planetary motion, also believed in a certain mathematical harmony and order in the way planets move in relation to each other.
