 As a counterpart to his interpretation of the visual and literary arts, Schopenhauer develops an account of music that coordinates it with the subjective pole of the universal subject-object distinction. Separate from the other traditional arts, he maintains that music is the most metaphysical art and is on a subjective, feeling-centered parallel with the Platonic Ideas themselves. Just as the Platonic Ideas contain the patterns for the types of objects in the daily world, music formally duplicates the basic structure of the world: the bass notes are analogous to inorganic nature, the harmonies are analogous to the animal world, and the melodies are analogous to the human world. The sounding of the bass note produces more subtle sonic structures in its overtones; similarly, inanimate nature produces animate life.
