I've always loved that music, in all its abstractness, can be explained mathematically. So much of what we feel when we hear a song is because of the phrasing -- which is simply the sequencing of chords, each of which are a combination of notes (wavelengths at differing frequencies). It's the quantitative difference between the notes and the variation of cadence combinations that make us feel happy, or sad, or unresolved.
