PURPOSE: To illustrate manipulation of vocal formants.
DESCRIPTION: Certain Tibetan monks are able to manipulate their vocal formants so that they sound like they are singing two notes at the same time. They sing a fundamental frequency of about 70 Hz, and manipulate their vocal system to produce f ormants at the fifth, tenth, etc. harmonics of 70 Hz. Because of this emphasis a note at 5x70Hz or 350 Hz sounds, two octaves and a major third above the fundamental. This music is part of certain religious rituals.
