Kargyraa
Kargyraa is a deep, "undertone" technique used in Tuvan
throat singing. The
vestibular folds or
false vocal folds are vibrated to produce an "undertone" exactly half the frequency of the fundamental produced by the
vocal folds, and the mouth cavity is shaped to select
harmonics of both the fundamental and the "undertone," producing from four to six pitches simultaneously.
