Ancient cosmology held that each of the planetary spheres corresponded to a different note in a universal musical scale. The tones emitted by the planets depended on the ratios of their different orbits in the same way that the length of a lyre-string determines its tone. The music of the spheres was contemplated by many respected philosophers, like Pythagoras, Plato, Pliny and Ptolemy. The English hermetic philospher Robert Fludd devised celestial scales that spanned three octaves, linking sub-planetary elemental worlds to angelic choruses beyond the stars.
