In this live demonstration, musician Bobby McFerrin uses audience participation to show that, when given two notes, the other notes of the pentatonic scale can be reliably elicited.

Mr. Maman's unpublished work (1987) revealed that he had assigned a
pitch to each command point on both yin and yang meridians by modulating
in musical 5ths through each meridian. This effectively assigned a
different pentatonic mode to each meridian with the key not of that mode
assigned to the element-within-the-element point.
There is agreement that the Five Voices describe functional relationships reflecting the order in which the tones are generated by modulating in fifths from a fundamental
Shang. Chip. Chih and Yu (adapted from the Chao-Mei-Pa, 1934). The generation of the Five Voices by fifths, and the twelve semitones in the chromatic series (six yin and six yang) represent the Five-Element Theory and yin/yang cosmology, respectively.
