Bobby McFerrin demonstrates the universality of the pentatonic scale and “audience expectations” in this entertaining video from the World Science Festival 2009. This was part of a larger event in the festival entitled Notes & Neurons.

If the notion of the universality of the pentatonic scale interest you, may I recommend the first of Leonard Bernstein‘s Norton Lectures, in which he relates the pentatonic scale (and varieties of it associated with different cultures) to the harmonic series.

Thanks to Pat Kane for flagging this up in Twitter.
