The Music of the Spheres
. . .
In ancient Greece, Pythagoras and his followers thought that celestial bodies made music. This diagram attempts to represent such theories about the earth’s relationship to other planets—an idea, based in physical truths and metaphysical beliefs, that the divine and poetic order of the universe could be known.
Pythagoras had already discovered the workings of musical pitch by way of vibration. In his book Fermat’s Enigma, author Simon Singh quotes fourth-century scholar Iamblichus to describe this account:
“Once, he was engrossed in the thought of whether he could devise a mechanical aid for the sense of hearing which would prove both certain and ingenious. Such an aid would be similar to the compasses, rules and optical instruments designed for the sense of sight. Likewise the sense of touch had scales and the concepts of weights and measures. By some divine stroke of luck he happened to walk past the forge of a blacksmith and listened to the hammers pounding iron and producing a variegated harmony of reverberations between them, except for one combination of sounds.” (14)
Pythagoras reportedly examined the hammers, and concluded that the hammers that were harmonious with one another shared a relationship in their respective weights—they were simple fractions such as one half or one quarter. Thus, he rationalized that 1:2 ratios produced an “octave” — the same note with a higher pitch. Other ratios produced different harmonies. This can be evidenced in string instruments, where strings of different lengths (ratios) produce different tones.
String instruments also make visible the vibrations that become sound. The human ear hears sounds when objects are in motion. Pluck a guitar string and watch the resulting vibrations and accompanying sound. Moving the string creates corresponding ripples of movement reverberating through its length, and through the air. These vibrations—sound waves—travel to the middle and inner ear, where the same frequencies of vibration are transmitted then amplified.
Pythagoras, extrapolating these effects, reasoned that, because objects produced sound when in motion, planets moving in orbit should also produce a sound. In the geocentric diagram above, there are eight steps from the earth to the “highest skies” (summum caelum). Between the earth and the moon, there is one full tone (tonus); between the moon and Mercury, one half tone; and between Venus and the sun, one and a half tones. He measured distance based on relative speed: faster moving planets were closer to the earth, and slower-moving planets farther away. These ratios corresponded to tonal musical intervals in the Pythagorean scale. (Plato, criticizing such theories, noted that “The error which pervades astronomy also pervades harmonics. The musicians put their ears in the place of their minds…” downplaying aural culture in his view.)

Thank you, so much, Cattle Dog. The Black Hole vibration sounds will leave a deep impression, from the zone far beyond mere words.
