Music and motion are closely related...If you ever watch a young kid sing along with music, they often wave their arms about or dance. Not because they've been taught, but probably becuase it is a natural response.
In electrically monitored tests, participants who are asked to listen to music and not move actually show increased signs of muscle activity, probably revelaing some deep relation between the two.
There have even been cases in which music can bring on epileptic fits in certain people. Sometimes they can even be brought on by simply recalling music in the person own mind...It's a scary thought, but it happens, and there is obviously something in our brain that tells our body to react to music.
