So, you think you're fancy with your pentatonic scale, do you?

World Science Festival 2009: Bobby McFerrin Demonstrates the Power of the Pentatonic Scale from World Science Festival on Vimeo.

Can you take over the freakin' world with it? Bobby McFerrin can. This is absolutely one of the coolest displays of the innate musicality in us. I truly believe, with mathematics, it is one of the higher order, ingrained processes that make us uniquely human...

Simple minor pentatonic scale...note the five pitches per octave. This shit is universal: According to good ole Wiki, it's in traditional Greek arrangements, Sami songs, Celtic jams, West Africa, American Jazz/Blues/Rock, Afro-Caribbean songs, Korea, China, Japan, India, ad nauseum.
