I just spent the last 30 minutes having my mind sufficiently blown by Vi Hart on the topic of 12-tone music, thanks to Boing Boing and my friend Alan. I think it's safe to say that 12-tone music isn't everyone's favorite stuff, although I was one of the oddballs in school who loved studying and performing it. Thankfully, Ms. Hart has made it accessible using laser bats, nursery rhymes, wit, and humor, and for good measure, she throws in some ideas about copyright and the meaning of life. (It's super-fun, but probably not for kids.) It's the best 30 minutes I've spent on YouTube in a long time. Maybe ever. Don't skip a minute. The last segment won't make sense without the rest, and the last part was pure joy for me.
Related to Stravinsky and the human brain's obsession with finding patterns, you should check out this Radiolab segment. You could skip to 7:33, but the beginning will help it make more sense: http://www.radiolab.org/2007/sep/24/sound-as-touch/
