They did a lot of illustrations of the points he was discussing, so this program isn't just a long book review, it is a lucid presentation of examples. For example, they played three versions of Beethoven's Moonlight Sonata at one point. One was very passionate, one was trimmed down to a metronome quality. The third had about 3/4 of the emotional elements layered back in. I could hear the differences because I'd played the piece for years. I thought the third version sounded best--the first was a little too over the top. But the point was that most people can tell the difference between the first and second versions because of hard-wiring in humans. The distinction between the first and third versions is more subtle and tends to be noticed by people with more experience with the music. It was a very effective discussion of how humans respond to music. Also, someone called in with a question about the song stuck in one's head. Levitin correctly identified this as an "ear worm" (all Mudcatter's know that one!) and discussed strategies for getting it out of your head. :)
