Music can “move” human beings, affect them physically, and arouse them. This can involve tensing muscles, nodding in time, vocalizing, weeping, swaying, or other type of movement. Motion and emotion are inseparably linked. (Storr, Anthony. Music and the Mind. p 183-188. NY: Ballantine Books, 1992.)

Humans appear to be the only species that spontaneously move in response to music. This may be due to the interplay between the auditory system (hearing) and motor system (movement). Studies have shown that just thinking about tapping out a rhythm lights up portions of the brain’s motor system. Even when people listen to music without moving any portion of the body, there is activity in brain regions that control movement. (Harris, Maureen. Music and the Young Mind. p 11.
