What I enjoy most about classical music is its unpredictability. Some people like it for its relative calm; others for its elevated spirit, its quest after the sublime; others for its depths of emotion; others for its intellectual demands. While all those are important to me too, I find listening to a truly rich piece of classical music like reading a good story--I don't know where it's going to take me next, and each place it takes me is new, fresh, unexpected. Yet a good classical piece is not simply a series of disorientations--it all makes sense in retrospect, and one can listen to it again and again with the same pleasure, just as one can read a story again and again to figure out how it all works. And each time one does, the emotions it triggers return, though shaded differently by one's knowledge of what's to come.
This piece tells a continually surprising and moving story with a simplicity and innocence that only heightens its richness. Listen to it in the foreground, not the background, and perhaps you'll see what I mean.
