Yeah, this is awesome:

I'm a music nerd.  And I fully believe that music is universal - it belongs to every culture, every people.  And I find it amazing that people just naturally sense music.  There are only eight notes in music - and those notes are not arbitrarily determined... they are found cross culturally.  And that, to me, is fascinating.

So while this video blows my mind, it really doesn't surprise me.  It's just one of those things that stands to reason.

Enjoy.
