The idea of assigning harmony to the cosmic bodies has been around for quite some time. Pythagoras, an ancient Greek philosopher and mathematician, is credited for coining the phrase, Harmony of the Spheres, also known as Music of the Spheres. At that time in the world, only 5 planets besides our own were known, along with 5 perfect solids, and 5 notes in the pentatonic scale. Those ancient Greeks believed in perfection in the universe and felt that this was no coincidence. In tribute to the idea, I offer these musical selections to our closest spheres of influence in the solar system: Earth, Moon, and Sun. Together they create cosmic harmony, and as a set are available at discount.
