Musica universalis (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 simply a
harmonic and/or
mathematical 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 
At the time, the Sun, Moon, and planets were thought to revolve around Earth in their proper spheres. The most thorough and imaginative description of the concept can be found in Dante's Divine Comedy. The spheres were thought to be related by the whole-number ratios of pure musical intervals, creating musical harmony. Johannes Kepler used the concept of the music of the spheres in his Harmonice Mundi in 1619, relating astrology (especially the astrological aspects) and harmonics.
The three branches of the Medieval concept of musica were presented by Boethius in his book De Musica:
In 2006, an experiment conducted by Greg Fox divided the orbital periods of the planets in half again and again until they were literally audible. The resultant piece was " Carmen of the Spheres". The principle of octaves in music states that, whenever a sound-wave is doubled or halved in frequency, it yields a super-octave or sub-octave pitch that is always perfectly consonant with the original one. This can be applied (through very large octave shifts) to any periodic cycle, such as the orbits of celestial bodies, to render an audible analogue.
Hinduism
Some
Surat Shabda Yoga Satgurus considered the music of the spheres to be a term synonymous with the
Shabda (also known as the
Audible Life Stream) in that tradition, because they considered
Pythagoras to be a Satguru as well.
Occultism
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
World of Thought, which is an ocean of harmony. It is also referred in
Esoteric Christianity that this is the place where it occurs the state of
consciousness called the "Second heaven."
