The '''''musica universalis''''' (literally '''universal music'''), also called '''music of the spheres''' or '''harmony of the spheres''', is a [[philosophy|philosophical]] concept that regards proportions in the movements of [[celestial bodies]]—the [[Sun]], [[Moon]], and [[planet]]s—as a form of [[music]]. The theory, originating in ancient Greece, was a tenet of [[Pythagoreanism]], and was later developed by 16th-century astronomer [[Johannes Kepler]]. Kepler did not believe this "music" to be audible, but felt that it could nevertheless be heard by the soul. The idea continued to appeal to scholars until the end of the [[Renaissance]], influencing many schools of thought, including [[humanism]].

The concept of the "music of the spheres" incorporates the [[Metaphysics|metaphysical]] principle that mathematical relationships express qualities or "tones" of energy that manifests in numbers, visual angles, shapes and sounds—all connected within a pattern of proportion. [[Pythagoras]] first identified that the [[Pitch (music)|pitch of a musical note]] is an inverse proportion to the length of the string that produces it, and that intervals between harmonious sound frequencies form simple numerical ratios.<ref>{{harvnb|Weiss|Taruskin|2008|page=[https://books.google.com/books?id=q1eobgND8H4C&pg=PA3 3]}}.</ref> Pythagoras proposed that the Sun, Moon and planets all emit their own unique hum based on their orbital revolution,<ref>{{harvnb|Rackham|1938|pages=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".</ref> and that the quality of life on Earth reflects the tenor of celestial sounds which are physically imperceptible to the human ear.<ref>{{harvnb|Houlding|2000|page=28}}: "The doctrine of the Pythagoreans was a combination of science and mysticism ... Like [[Anaximenes of Miletus|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".</ref> 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.<ref>{{harvnb|Davis|2010|page=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".</ref>

[[Aristotle]] characterized the theory as follows:<ref name=Aristotle>{{cite book |chapter-url=http://classics.mit.edu/Aristotle/heavens.2.ii.html |title=On the Heavens |chapter=Book 2, Part 9 |author=Aristotle |translator= J. L. Stocks}} Hosted at the Internet Classics Archive.</ref>

{{bq|Some thinkers suppose that the motion of bodies of that size must produce a noise, since on our earth the motion of bodies far inferior in size and in speed of movement has that effect. Also, when the sun and the moon, they say, and all the stars, so great in number and in size, are moving with so rapid a motion, how should they not produce a sound immensely great? Starting from this argument and from the observation that their speeds, as measured by their distances, are in the same ratios as musical concordances, they assert that the sound given forth by the circular movement of the stars is a harmony. Since, however, it appears unaccountable that we should not hear this music, they explain this by saying that the sound is in our ears from the very moment of birth and is thus indistinguishable from its contrary silence, since sound and silence are discriminated by mutual contrast. What happens to men, then, is just what happens to coppersmiths, who are so accustomed to the noise of the smithy that it makes no difference to them.}}

Aristotle rejected the idea, however, as incompatible with his own cosmological model, and on the grounds that "excessive noises ... shatter the solid bodies even of inanimate things", and therefore any sounds made by the planets would necessarily exert a tremendous physical force upon the body.<ref name=Aristotle/>

[[Boethius]], in his influential work ''De Musica'', described three categories of music:<ref name=":2">Boethius. ''De Institutione Musica'', I. 2.</ref>

* ''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)
Boethius believed that ''musica mundana'' could only be discovered through the intellect, but that the order found within it was the same as that found in audible music, and that both reflect the beauty of God.{{sfn|Scruton|2013|pages= 249–250}}

== ''Harmonices Mundi'' ==
''{{main|Harmonices Mundi}}''

''Musica universalis''—which had existed as a metaphysical concept since the time of the Greeks—was often taught in [[quadrivium]],{{sfn|Voelkel|1994|pages=59–60}} and this intriguing connection between music and astronomy stimulated the imagination of [[Johannes Kepler]] as he devoted much of his time after publishing the [[Mysterium Cosmographicum|''Mysterium'' ''Cosmographicum'']] (Mystery of the Cosmos), looking over tables and trying to fit the data to what he believed to be the true nature of the cosmos as it relates to musical sound.{{sfn|Kepler|1596}}{{sfn|Caspar|1993}} In 1619, Kepler published ''Harmonices Mundi'' (literally Harmonies of the World), expanding on the concepts he introduced in ''Mysterium'' and positing that [[Interval (music)|musical intervals]] and [[Harmony|harmonies]] describe the motions of the six known planets of the time.{{sfn|Kepler|1997}} He believed that this harmony—while inaudible—could be heard by the soul, and that it gave a "very agreeable feeling of bliss, afforded him by this music in the imitation of God." In ''Harmonices'', Kepler—who took issue with Pythagorean observations—laid out an argument for a Christian-centric creator who had made an explicit connection between geometry, astronomy, and music, and that the planets were arranged intelligently.{{sfn|Caspar|1993}}
[[File:Planetary_Musical_Scales_from_Harmony_of_the_Worlds.jpg|thumb|Page from Kepler's ''Harmonices Mundi''. The scales of each of the six known planets, and the moon, placed on five-line staffs.]]
''Harmonices'' is split into five books, or chapters. The first and second books give a brief discussion on [[regular polyhedron|regular polyhedra]] and their [[Congruence (geometry)|congruences]], reiterating the idea he introduced in ''Mysterium'' that the five regular solids known about since antiquity define the orbits of the planets and their distances from the sun. Book three focuses on defining musical harmonies, including [[consonance and dissonance]], intervals (including the problems of just tuning), their relations to string length which was a discovery made by Pythagoras, and what makes music pleasurable to listen to in his opinion. In the fourth book, Kepler presents a metaphysical basis for this system, along with arguments as to why the harmony of the worlds appeals to the intellectual soul in the same manner that the harmony of music appeals to the human soul. Here, he also uses the naturalness of this harmony as an argument for [[heliocentrism]]. In book five, Kepler describes in detail the orbital motion of the planets and how this motion nearly perfectly matches musical harmonies. Finally, after a discussion on [[astrology]] in book five, Kepler ends ''Harmonices'' by describing his [[Third law of planetary motion|third law]], which states that—for any planet—the cube of the semi-major axis of its elliptical orbit is proportional to the square of its orbital period.{{sfn|Kepler|1997}}

In the final book of ''Harmonices'', Kepler explains how the ratio of the maximum and minimum [[Angular velocity|angular speeds]] of each planet (i.e., its speeds at the perihelion and aphelion) is very nearly equivalent to a consonant musical interval. Furthermore, the ratios between these extreme speeds of the planets compared against each other create even more mathematical harmonies.{{sfn|Kepler|1997}} These speeds explain the [[Eccentricity (mathematics)|eccentricity]] of the orbits of the planets in a natural way that appealed to Kepler's religious beliefs in a heavenly creator.{{sfn|Caspar|1993}}

While Kepler did believe that the harmony of the worlds was inaudible, he related the motions of the planets to musical concepts in book four of ''Harmonices''. He makes an analogy between comparing the extreme speeds of one planet and the extreme speeds of multiple planets with the difference between [[Monophonic music|monophonic]] and [[Polyphony|polyphonic]] music. Because planets with larger eccentricities have a greater variation in speed they produce more "notes." Earth's maximum and minimum speeds, for example, are in a ratio of roughly 16 to 15, or that of a semitone, whereas Venus' orbit is nearly circular, and therefore only produces a singular note. Mercury, which has the largest eccentricity, has the largest interval, a minor tenth, or a ratio of 12 to 5. This range, as well as the relative speeds between the planets, led Kepler to conclude that the [[Solar System]] was composed of two basses ([[Saturn]] and [[Jupiter]]), a tenor ([[Mars]]), two altos ([[Venus]] and [[Earth]]), and a soprano ([[Mercury (planet)|Mercury]]), which had sung in "perfect concord," at the beginning of time, and could potentially arrange themselves to do so again.{{sfn|Kepler|1997}} He was certain of the link between musical harmonies and the harmonies of the heavens and believed that "man, the imitator of the Creator," had emulated the polyphony of the heavens so as to enjoy "the continuous duration of the time of the world in a fraction of an hour."{{sfn|Caspar|1993}}

Kepler was so convinced of a creator that he was convinced of the existence of this harmony despite a number of inaccuracies present in ''Harmonices''. Many of the ratios differed by an error greater than simple measurement error from the true value for the interval, and the ratio between Mars' and Jupiter's angular velocities does not create a consonant interval, though every other combination of planets does. Kepler brushed aside this problem by making the argument, with the math to support it, that because these [[Ellipse|elliptical]] paths had to fit into the regular solids described in ''Mysterium'' the values for both the dimensions of the solids and the angular speeds would have to differ from the ideal values to compensate. This change also had the benefit of helping Kepler retroactively explain why the regular solids encompassing each planet were slightly imperfect.{{sfn|Caspar|1993}}  Philosophers posited that the Creator liked variation in the celestial music.<ref>Plant, David, "[https://www.skyscript.co.uk/kepler.html Kepler and the Music of the Spheres]", ''Skyscript''; accessed 2022.11.20.</ref>

Kepler's books are well-represented in the [[Library of Sir Thomas Browne]], who also expressed a belief in the music of the spheres:<ref>Browne, Thomas (1643). ''[[Religio Medici]]''. Part 2, section 9.</ref>
<blockquote>For there is a musicke where-ever there is a harmony, order or proportion; and thus farre we may maintain the musick of the spheres; for those well ordered motions, and regular paces, though they give no sound unto the eare, yet to the understanding they strike a note most full of harmony. Whatsoever is harmonically composed, delights in harmony.</blockquote>

==Orbital resonance==
{{Expand section|date=March 2023}}
In celestial mechanics, [[orbital resonance]] occurs when orbiting bodies exert regular, periodic gravitational influence on each other, usually because their orbital periods are related by a ratio of small integers. This has been referred to as a "modern take" on the theory of ''musica universalis''.{{sfn|Maltagliati|2021}} This idea has been further explored in a musical animation, created by an artist at the [[European Southern Observatory]], of the planetary system [[TOI-178]], which has five planets locked in a chain of orbital resonances.{{sfn|Maltagliati|2021}}<ref>[https://www.youtube.com/watch?v=-WevvRG9ysY "Artist's animation of the TOI-178 orbits and resonances"].

==Cultural influence==
[[William Shakespeare]] makes reference to the music of the spheres in ''[[The Merchant of Venice]]:''<ref>Shakespeare. ''The Merchant of Venice''. [http://shakespeare.mit.edu/merchant/merchant.5.1.html Act 5, Scene 1].</ref>

{{poem quote |text=Sit, Jessica. Look how the floor of heaven
Is thick inlaid with patines of bright gold:
There's not the smallest orb which thou behold'st
But in his motion like an angel sings,
Still quiring to the young-eyed cherubins;
Such harmony is in immortal souls;
But whilst this muddy vesture of decay
Doth grossly close it in, we cannot hear it.}}

In the 1910s, Danish composer [[Rued Langgaard]] composed a pioneering orchestral work titled ''[[Music of the Spheres (Langgaard)|Music of the Spheres]]''.

[[Paul Hindemith]] also made use of the concept in his 1957 opera, ''[[Die Harmonie der Welt]]'' ("The Harmony of the World"), based upon the life of Johannes Kepler.

A number of other modern compositions have been inspired by the concept of ''musica universalis''. Among these are ''Harmony of the Spheres'' by [[Neil Ardley]], live-only track <nowiki>''</nowiki>La musique des sphères<nowiki>''</nowiki> by [[Magma (band)|Magma]]/VanderTop, ''[[Music of the Spheres (Mike Oldfield album)|Music of the Spheres]]'' by [[Mike Oldfield]], ''[[The Earth Sings Mi Fa Mi]]'' by [[The Receiving End of Sirens]], ''[[Music of the Spheres (Ian Brown album)|Music of the Spheres]]'' by [[Ian Brown]], "[[Cosmogony (song)|Cosmogony]]" by [[Björk]], and the [[Coldplay]] album ''[[Music of the Spheres (Coldplay album)|Music of the Spheres]]''.

''[[Music of the Spheres (Destiny)|Music of the Spheres]]'' was also the title of a companion piece to the video game ''[[Destiny (video game)|Destiny]]'', composed by [[Martin O'Donnell]], [[Michael Salvatori]], and [[Paul McCartney]].<ref>{{Cite web |last=Schreier |first=Jason |date=May 1, 2018|title=Bungie Says It Will Release Destiny's Music of the Spheres, To Composer's Surprise|url=https://kotaku.com/bungie-says-it-will-release-destinys-music-of-the-spher-1825691821|website=Kotaku|language=en-us}}</ref>

A [[concert band]] arrangement by [[Philip Sparke]] has also used the name "Music of the Spheres" and is often used as a set test piece, with a notable studio performance recorded by the [[YBS Band]] while led by maestro [[Professor David King]].

Reference is made to the music of the spheres in the short story ''[[The Horror in the Museum]]'' by [[H. P. Lovecraft]].<ref>{{Cite web |title="The Horror in the Museum" by H. P. Lovecraft for Hazel Heald |url=https://www.hplovecraft.com/writings/texts/fiction/hm.aspx |access-date=2023-07-05 |website=www.hplovecraft.com}}</ref>

In the video game ''[[Overwatch]]'', the playable character [[Sigma (Overwatch)|Sigma]] often claims the universe is singing to him.

During the 2008 [[BBC Proms]] [[Doctor Who]] segment, a short interactive mini-episode starring [[David Tennant]] and written by showrunner [[Russell T Davies]] titled ''[[Music of the Spheres (Doctor Who)|Music of the Spheres]]'' was played. This sees the Doctor attempting to compose ''Ode to the Universe'', basing his works on the Music of the Spheres. This piece continues the metaphysical theories of the ''musica universalis'' by arguing that the audience themselves are part of the composition.
