Where does the musical scale come from? Is it merely a human invention? In 1619, the astronomer Johannes Kepler showed in his "The Harmony of the World" that not only are the ratios that form the major and minor scales coherent with the principles of constructive geometry, but they are built into the very stars themselves—that is, the motions of the planets of our solar system, as moved by their choral conductor, our Sun.
