It's a weird video. I'll be the first to say that. This gal posts posts in which she doodles math, basically. And she's a 'personality.' And her singing is weird. But this post is FASCINATING. She talks about modernist composers use of 12 tonal scales (is that the right word?) and what that has to do with art, creativity, math, pattern recognition. All the interesting stuff!
So watch it. Or don't! See if I care.
Don't wanna watch that? Fine. I bet you'll watch this nonsense.
(Oh Jack Black, I can't stay mad at you.)
