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

During the “Notes & Neurons: In Search of a Common Chorus” at the World Science Festival,  Bobby McFerrin utilizes the five scale/pentatonic scale to demonstrate universality by using the  audience as his instrument. Very akin to the performance art espoused by John Cage.
