The Solar System set to music: via Brainpickings

Daniel Starr-Tambor’s Mandala — a remarkably dimensional musical composition created by assigning each planet in the Solar System a particular note along the natural harmonic series, starting with Mercury’s B and going all the way up by two octaves and a ninth to Pluto’s C#. The composition is a palindrome, which means it can be played the same way in either direction, and, with more than 62 vigintillion individual notes, it’s the longest palindrome in existence — by far. At the accelerated tempos of the Solar System, it would continue without repetition for over 532.25 septendecillion years — a sort of soundtrack for near-infinity.
