How does music alter your conciousness?

Music seems to have this weird ability to worm it’s way into your brain, and make you feel different. It can calm you down; it can put you in a trance; it can excite you; it can involve you.

How does it do all that? What kind of impacts do you think music has on your consciousness? Does it affect your brain (if you think brain and conciousness are different)? What’s your experience. What’s your explanation, if you have one.
