Musicauniversalis (lit. universal music, or music of the spheres) is an ancient
philosophical concept that regards proportions in the movements of celestial bodies—the Sun, Moon, and planets—as a form of musica (the Medieval Latin name for music). This 'music' is not literally audible, but a harmonic and/or mathematical and/or religious concept. The Greek mathematician and astronomer Pythagoras is frequently credited with originating the concept, which stemmed from his semi-mystical, semi-mathematical philosophy and its associated system of numerology of Pythagoreanism. According to Johannes Kepler, the connection between geometry (and sacred geometry), cosmology, astrology, harmonics, and music is through musica universalis .
