McFerrin's enduring reputation as the one-hit wonder behind "Don't Worry, Be Happy" significantly undersells his actual legacy in music, as a brilliant singer and percussionist, a ten-time Grammy winner and a general jazz and pop savant. You can see his genius far more acutely on display in this clip from the World Science Festival, in which McFerrin essentially plays the auditorium crowd like a piano, literally jumping from note to note as the crowd learns not only about the awesome power of the pentatonic scale, but how music is far more innate and unifying than we could possibly understand. Doesn't even need a whistle hook or a Robin Williams cameo to do it, either.
