It’s origin and Mechanisms
Musical art of the Tuvans, people inhabiting the western Sayans in the Upper Enisey, is notable for its big originality.
The Tuvan singing presents a special interest. The peculiarity of the art of the Tuvan musicians lies in the fact that the singer simultaneously extracts by voice, two or even three sounds. The solo two/three-voice singing emerges thanks to the simultaneous sounding of the fundamental which has a gutteral timbre colouring and its upper overtones which are caught and amplified by the head resonator. For all this the fundamental performs the function of the bass pedal and the upper subsounds also carefully draw a crystal pure melody on natural overtones in a high register. Sometimes a special additional subsound joins the lower sound. In such cases this produces the effect of the solo three-voice singing.
There exist a number of styles of the Tuvan throat-singing, sometimes a singer can perform several styles. The styles differ by the pitch of the sound extraction and timbre peculiarities of the phonation connected with it. Each style has its own distinctive expressive properties.
The highest, brightest style is ‘sygyt’ in which the highest register of the voice is used. The head subsounds have a singing ‘glass’ timbre shade.
Songs in the ‘khoomei’ style sound somewhat softer. The timbres in the style are slightly muffled.
Singing in the ‘borbannadyr’ style attracts by its velvet sound. The bass pedal in the middle register has an additional subsound affecting the quint overtone over an octave, as a result of that, there appears a peculiar three-voice singing.
Usually the performing of the melody with corresponding words foregoes an inclusion of the head subsounds on the bass pedal. There are a lot of different songs that can be performed in each style.
In a number of cases, the throat singing can be accompanied by an instrument, either the stringed pizzicato – doshpuluur or the stringed bow – igil, byzaanchy.
In every-day life the throat singing songs are usually performed while a herder, watching a flock of sheep, is having a rest, the throat-singing in the mountains can be heard far away. According to a singer he is sending greetings with his song to his people who are staying in a yurt far away from the pasture.

Explanations on throat singing by Steve Sklar,
organizer of Nikolay’s tour to Canada
All styles of Tuvan Khoomei involve controlled tension in and manipulation of the diaphragm, throat, and mouth. However, there are great differences between the different types of throat-singing; for example, some styles are multiphonic whereas other styles are not. Even this description must take into consideration the hearing, or conditioned hearing of the listener as much as the intention and execution of the singer.
There is no real consensus on Khoomei categories; this is a complicated issue due to a number of confusing factors. For one thing, affecting western scholars, there have to date been very few texts about Khoomei in Western European languages. The most commonly cited source was translated from Tuvan Folk Music, a book published in 1964 by A. N. Aksenov, a Russian composer who surveyed Tuvan Khoomei styles in the 1940-50s. More recently, there have been such resources such as Mark van Tongeren’s quite interesting Overtone Singing, various CD liners of varying quality and accuracies, and WWW sites.
There are major discrepancies between Aksenov’s descriptions and other older sources, and those of other more contemporary observers, and several plausible explanations. One is that Aksenov’s survey of Tuvan styles was limited in scope, though he was a highly educated and skilled composer and musician, who seemed to take his research most seriously. Although a definite factor, it is also apparent that there has been an appreciable development and metamorphosis of common Khoomei styles since Aksenov’s time. Also, many performances now include mixtures of styles much more extensively than in the past. Whereas many singers in the old days tended to sing mostly in one or two styles, and there was greater regional differentiation, many modern singers perform in numerous styles, hybrids, and develop their own takes on “the classics.”
So, although there is no widespread agreement, many contemporary Khoomei cognoscenti designate three or five major styles:
As noted below, #4 and 5, Borbangnadyr and Ezengileer are sometimes considered to be proper styles, and sometimes to be ornamentations added to Khoomei, Kargyraa, or Sygyt. I would add to the top of the list Xorekteer, as it underlies most of the various styles.
Xorekteer means singing with the chest voice… Now, this can be confusing to beginners: What does “chest voice” mean? And why isn’t it the “throat voice?” This term can carry several meanings. It can be used, like khoomei, to mean ALL THROAT-SINGING, in any style. It can also be used as a metaphor for “with feeling,” as in “more heart.” Plus, it can refer both to the feeling of pressure one feels when throat-singing, and also to chest resonance, which is obvious in person but not on recordings.
In its common sonic sense, “Chest voice” has a totally different meaning than the western vocal context, and the two should not be confused. Those familiar with Tuvan music have noticed that often entire songs are sung with this voice. It usually serves as the springboard to launch into khoomei style and sygyt.
Khoomei is not only the generic name given to all throat-singing styles, but also to a particular style of singing. Khoomei is a soft-sounding style, with clear but diffused-sounding harmonics above a fundamental usually within the low-mid to midrange of the singer’s voice. In Khoomei style, there are 2 or more notes clearly audible.
The stomach remains here fairly relaxed, and there is less laryngeal tension than harder-sounding Sygyt. The tongue remains seated quietly between the lower teeth. The pitch of the melodic harmonic is selected by moving the root of the tongue and the attached epiglottis.
Phrasing and ornamentation come from a combination of throat movements and lip movements. Lips generally form a small “O.” The combination of lip, mouth and throat manipulations make a wide spectrum of tones and effects possible.
Kargyraa is usually performed low in the singer’s range. There are two major styles of Kargyraa, Mountain (dag) and Steppe (xovu). Both feature an intense croaking tone, very rich in harmonics. This technique is related technically to Tibetan harmonic chanting.
|Nothing feels like Kargyraa; you really feel a “mouthful of sound.” The term refers to all styles of singing which simultaneously use both the vocal and ventricular folds inside the larynx, as dual sound-sources. When the larynx is constricted slightly just above the level of the vocal folds while the vocal folds are engaged, the ventricular folds will usually resonate, producing the second sound source. The ventricular folds’ fundamental vibrates at half the speed of the vocal folds, producing the extra sound one octave lower than the usual voice.The ventricular folds also produce many midrange and upper harmonics.|
While not yet proved, I suspect that each set of folds produces its own harmonic series, which intereact and are affected by the formants of the vocal system. Careful listeners will note the “constant” sound produced by the vocal folds, and a periodical, pulsating complex of sounds created by the ventricular folds. Kargyraa often sounds more traditional, or authentic, when the vocal folds are in Xorekteer mode, as above, and when the sound is somewhat restrained, rather than freely exiting the mouth.
Kargyraa is the one Tuvan style that I know of that is closely linked to vowel sounds; in addition to various throat manipulations, the mouth varies from a nearly closed “O” shape to nearly wide open. Except for the throat technique, this style is vaguely related to western overtone singing styles that use vowels and mouth shapes to affect the harmonic content. However, unlike most western styles, there is no dependable correlation between the vowel and the pitch. Generally, western overtone singers link pitch to the vowel, so that “ooo” gives the lowest harmonic, and rise in pitch from “ooo” to “o” to “ah” to “a” to “ee,” and so on. In Kargyraa, an “ah” can be higher than “a”, etc.
Dag (Mountain) Kargyraa is usually the lower of the styles in pitch, and often includes nasal effects; this sometimes sounds like oinking! It should feature strong low-chest resonance, and not too much throat tension.
Xovu (Steppe) Kargyraa is usually sung at a higher pitch, with more throat tension and less chest resonance. It also has a generally raspier sound.
Sygyt is usually based on a mid-range fundamental. It is characterized by a strong, even piercing, harmonic or complex of harmonics above the “fundamental,” and can be used to perform complex and very distinct melodies, with a tone similar to a flute. The ideal sound is called “Chistii Zvuk,” Russian for clear sound. Part of achieving this ideal is learning to filter out unwanted harmonic components.
For sygyt, you must increase the tension a bit at the same place as in khoomei. The tongue rises and seals tightly all around the gums, just behind the teeth. A small hole is left on one side or the other, back behind the molars, then you direct the sound between the teeth (which produces sharpening effect) and the cheek towards the front of the mouth. With your lips, form a “bell” as in a clarinet or oboe, but not centered; rather off just a bit to the side of your mouth where you direct the sound from that hole in the back. You change pitch with the same technique as khoomei, and the rest of the tongue moves slightly to accommodate this action. The raised tongue serves as a filter to remove more of the lower harmonics, and in sygyt, it is possible to nearly remove the fundamental.
Borbangnadyr is not really a style in quite the same sense as sygyt, kargyraa, or khoomei, but rather a combination of effects applied to one of the other styles. The name comes from the Tuvan word for rolling, and this style features highly acrobatic trills and warbles, reminiscent of birds, babbling brooks, etc. While the name Borbangnadyr is currently most often used to describe a warbling applied to sygyt, Sygyttyng Borbangnadyr, it is also applied to some lower-pitched singing styles, especially in older texts.
Ezengileer comes from a word meaning “stirrup,” and features rhythmic harmonic oscillations intended to mimic the sound of metal stirrups clinking to the beat of a galloping horse. The most common element is the “horse-rhythm” of the harmonics, produced by a rhythmic opening-and-closing of the velum. The velum is the opening between the pharynx and the nasal sinuses. The velum is not named, but is located just to the right of the soft palate, between the nasopharynx and oropharynx. Or, if you prefer, you will recognize it as the location of Postnasal Drip.
