I’ve heard it said that the essence of music is to make people enjoy patterns without realizing it. As far as I can tell, this is true. I can’t grasp music, whether I hear it, see a sheet of notes or play Guitar Hero. It’s beyond me, but I like to listen.
As fans of ’80s sci-fi/comedies know, music can do something else: let you time travel. Not literally, I mean, but the effect can be just as real as if it were.
