There is no one part of the brain which recognizes or responds emotionally to music. Instead, there are many different parts responding to different aspects of music: to pitch, to frequency, to timbre, to tonal intervals, to consonance, to dissonance, to rhythm, to melodic contour, to harmony.

Music, uniquely among the arts, is both completely abstract and profoundly emotional. It has no power to represent anything particular or external, but it has a unique power to express inner states or feelings. Music can pierce the heart directly; it needs no mediation.
