." The whole theory started to go awry when the Enlightenment scientists discovered that the earth was not in fact the center of the universe, though some like Copernicus tried to keep it relevant by explaining that Jupiter had an entire choir of moons. , Aristotle criticised the notion that celestial bodies make a sound in moving in the context of his own cosmological model:. The deeper affinity between mathematics and music, though, is less consoling and more challenging: The modern concept of a higher-order number begins with St. Augustine’s fifth-century treatise on music, and a red thread links it to Leibniz’ invention of the calculus in the seventeenth. Indeed , given the common source  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 differed from 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. Codified by Boethius in De Institutione Musica around the year 500, this cosmology classed music into three kinds: musica mundana, the music made by the rotations of the heavenly bodies’ concentric spheres; musica humana, the harmonies holding together man's body and spirit; and finally, musica instrumenta, the music made by man in imitation of the former two. He was born in Rome to an ancient and important family which included emperors Petronius Maximus and Olybrius and many consuls. It is not surprising that ancient musical treatises such as Boethius's De musica A small number of recent compositions either make reference to or are based on the concepts of Musica Universalis or Harmony of the Spheres. ), The anguish caused by the appearance of irrational numbers in musical tuning cannot be overstated. 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? 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), which had sung in “perfect concord,” at the beginning of time, and could potentially arrange themselves to do so again. 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. In De Musica, Augustine presents a hierarchy of rhythm that begins with “sounding numbers”—the rhythm we actually hear—followed by “memorized rhythms,” that is, the mind’s recognition and remembrance of a pattern. We do not know exactly when musicians began altering, or “tempering,” musical intervals to subordinate nature to the requirements of artifice. At the University of Padua, Prosdocimus de Beldemandis showed in 1425 that Pythagorean calculations could divide the octave into twelve half-tones, identifying all the accidentals required to build a scale starting on any tone. In addition, next to the billboard is a Rover car with the license plate “FFTF2024”.
