Harmony is the essence of music. Even if deliberately making noise with the intention of its being non-sensical, chaotic or unordered, this very act of expression is at the very least an admission the act itself has purpose and a means, and thus resides within a greater order. Likewise, discerning order even in seeming chaos or randomness is a finding of harmony.
However incomprehensibly complex the universe may seem at times, its machinations occur within the confines of a universal law, or harmony. Harmony is understanding, and music is the bond between incomprehension and understanding.
