The theory of music traces its roots to the earliest intellectual pursuits of the human species. When humankind sought to understand the cosmos, it did so through a science of harmonic tone relationship. It sought to both explain and experience the universe as a fundamental vibration, a Primal Sound, which manifested itself in the human world through a relationship of tones. It was understood that through developing ones’ sensitivity to harmonic relationships, a person could come to understand and experience the harmony between heaven and earth. This, in turn, would aid in creating a harmony within the individual and within society.
