Musica universalis (literally universal music), also called Music of the spheres or Harmony 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 term for music). This "music" is not usually thought to be literally audible, but a harmonic, mathematical or religious concept. The idea continued to appeal to thinkers about music until the end of the Renaissance, influencing scholars of many kinds, including humanists. Further scientific exploration has determined specific proportions in some orbital motion, described as Orbital resonance.
The Music of the Spheres incorporates the metaphysical principle that mathematical relationships express qualities or "tones" of energy which manifest in numbers, visual angles, shapes and sounds – all connected within a pattern of proportion. Pythagoras first identified that the pitch of a musical note is in proportion to the length of the string that produces it, and that intervals between harmonious sound frequencies form simple numerical ratios. In a theory known as the Harmony of the Spheres, Pythagoras proposed that the Sun, Moon and planets all emit their own unique hum (orbital resonance) based on their orbital revolution, and that the quality of life on Earth reflects the tenor of celestial sounds which are physically imperceptible to the human ear. Subsequently, Plato described astronomy and music as "twinned" studies of sensual recognition: astronomy for the eyes, music for the ears, and both requiring knowledge of numerical proportions.
- musica mundana (sometimes referred to as musica universalis)
- musica humana (the internal music of the human body)
- musica quae in quibusdam constituta est instrumentis (sounds made by singers and instrumentalists)
According to Max Heindel's Rosicrucian writings, the heavenly "music of the spheres" is heard in the Region of Concrete Thought, the lower region of the mental plane, which is an ocean of harmony.
Use in recent music
A small number of recent compositions either make reference to or are based on the concepts of Musica Universalis or Harmony of the Spheres. Among these are Music of the Spheres by Mike Oldfield, Om by the Moody Blues, The Earth Sings Mi Fa Mi album by The Receiving End of Sirens and Björk's single "Cosmogony", included in her 2011 album Biophilia.

- Pliny the Elder (77) pp.277-8, (II.xviii.xx): "…occasionally Pythagoras draws on the theory of music, and designates the distance between the Earth and the Moon as a whole tone, that between the Moon and Mercury as a semitone, .... the seven tones thus producing the so-called diapason, i.e.. a universal harmony".
- Houlding (2000) p.28: "The doctrine of the Pythagoreans was a combination of science and mysticism… Like Anaximenes they viewed the Universe as one integrated, living organism, surrounded by Divine Air (or more literally 'Breath'), which permeates and animates the whole cosmos and filters through to individual creatures … By partaking of the core essence of the Universe, the individual is said to act as a microcosm in which all the laws in the macrocosm of the Universe are at work".
- Davis (1901) p.252. Plato’s Republic VII.XII reads: "As the eyes, said I, seem formed for studying astronomy, so do the ears seem formed for harmonious motions: and these seem to be twin sciences to one another, as also the Pythagoreans say".
