This is your brain on music

The author of one of the books I've wanted to read for a while--Daniel Levitin, "This is your brain on music"--held a lecture Thursday in Princeton, so I ditched work a little early to check it out.
It was the first time in a long time I found myself in a lecture hall, and I liked it! I found it interesting how many people had their laptops out (and also was surprised how many of those were macs).
Anyway, the book is about how our brains interpret music. Basically, we learn the language of our culture's music before we are five, and we have the greatest faculty learning musical instruments before we are 10 to 12. So, I guess it makes sense that I'm starting to bring my gee-tar up to my nephews so that they can make some noise.
One thing he suggests is that music expresses emotion more dynamically than other forms of communication. Makes sense. How is it that we can feel so many emotions from hearing one piece of music? How is it that once we relate to that piece of music, it stays with us forever? I just don't believe other forms of communication have that power.
Such an interesting topic, and I can't wait to read the book!
