Kargyraa
(In Cyrillic: Каргыраа) The more deep sounding style of throat singing is known as Kargyraa (pronounced Kar-gi-ra). Kargyraa has a deep, almost growling sound to it and is technically related to Tibetan Buddhist chant and has some similarities with vocal fry. It uses both the vocal and the vestibular folds (also known as "false vocal chords") simultaneously, creating two connected sources of sound.
By constricting the larynx, the vestibular folds can be brought together (adducted) and, under certain conditions, vibrate. It can produce an undertone exactly half the frequency of the fundamental produced by the vocal folds. Therefore, for each second vibration of the vocal folds, the vestibular fold will complete a whole vibration cycle. While the larynx generates such rich sound, the mouth cavity may be shaped, just like in the manipulation of vowels, to select some particular harmonics, resulting in a sound that may be perceived as having different pitches simultaneously.
This vocal mechanism has been only recently elucidated and shown to be similar to the chant practiced in Tibet by the Gyuto monastery and other Buddhist orders.
There are two types of Kargyraa: Dag, or mountain, and Xovu, or steppe. The Dag style is deeper and has more nasal effects, while Xovu is raspier and sung at a higher pitch with more throat tension and less chest resonance. There are also the distinctive kargyraa styles of Vladimir Oidupaa and Albert Kuvezin, the latter also bearing the name kanzat. This is sometimes described as the howling winds of winter or the plaintive cries of a mother camel after losing her calf.
