why do we feel the chill that (in effect) says we have resolved a whole lot of dangling uncertainty when listening to a piece of music, or viewing a piece of theater, that we have experienced many times in the past? A full treatment of this would take us too far afield, but the key idea is that the power of great music (and great literature) lies in its ability to lead us through a staged process that first reliably builds up and then reliably resolves expectations.
