While I was busy researching for this paper, I stumbled upon a poem by Robert Morgan titled “Music of the Spheres”:
The first music we don't hear but know, is inner, the rings around atoms singing, the bright levels in matter revealed by colors through spectrum scales all up and down the quantum ladder in fireworks of the inner horizons, each zone voicing its wavelength with choirs in the tiny stadiums of harmony of the deeper galaxies, ancient octaves and intervals, lit cities within every speck of substance.
