Abstract

Mongolian “throat singing” can be performed in different modes. In Mongolia, the bass-type is called Kargyraa. The voice source in bass-type throat singing was studied in one male singer. The subject alternated between modal voice and the throat singing mode. Vocal fold vibrations were observed with high-speed photography, using a computerized recording system. The spectral characteristics of the sound signal were analyzed. Kymographic image data were compared to the sound signal and flow inverse filtering data from the same singer were obtained on a separate occasion. It was found that the vocal folds vibrated at the same frequency throughout both modes of singing. During throat singing the ventricular folds vibrated with complete but short closures at half the frequency of the true vocal folds, covering every second vocal fold closure. Kymographic data confirmed the findings. The spectrum contained added subharmonics compared to modal voice. In the inverse filtered signal the amplitude of every second airflow pulse was considerably lowered. The ventricular folds appeared to modulate the sound by reducing the glottal flow of every other vocal fold vibratory cycle.

What is throat singing?

Author: Robin Öberg

Abstract

In southern Siberia there is a culture of throat singing, a singing technique where a person can create two different and clearly audible tones at the same time. This throat singing phenomenon has flowed from the Tuvan republic in Russia out into the entire world. Persons of different ethnic ori­gins sing and teach throat singing to persons from all kinds of nations, thus all kinds of persons come in contact with the throat singing phenomenon. Questions that seem to naturally arise from this are: How is throat singing used by these persons, how does it play a part in their lives?

This study begins with a historical background to the phenomenon of throat singing, introducing the important terms and concepts, then it goes into the more scientific analysis, showing phenomenologically how a heterogeneous group uses throat singing in its/their ontology, and then concluding it all by putting it all together, creating a model of a being of throat singing.  In otherwords, this is a first step towards a complete understanding of the phenomena of throat singing, andthis first step takes the approach from the experience of the individual.

With a phenomenological method of analysis, Meaning Constitution Analysis, the different aspects of throat singing isexposed by showing the meanings associated with it. There has not been any similar study as this before, all the previous data using throat singing without definition is arbitrary. With the results ofthis study, even quantitative surveys can be used to further understand the phenomenon of throat singing.

1 IntroductionThis study will demonstrate that the being of throat singing is, among other things; being usedaround Altai Mountains in Siberia, being used to heal the earth, being used to create music, andbeing used to learn to throat sing together with others. This will be done by looking at how a groupof persons create meaning towards throat singing by their individual way of using and thinkingabout it.1.1 Short background to throat singingThe Tuva1 region in southern Siberia have always had natural barriers, like mountains, desert andrivers, that have for a long time made the country more or less inaccessible by outside visitors.During the larger part of the twentieth century Tuva was also willingly a part of the Soviet union,which created political barriers for visitors from the other side of the iron curtain. (Humphrey1980:1-4) Towards the latter part of the twentieth century Tuva was changed into an autonomousrepublic in Russia. This came to open to the borders internationally, both for tuvinians and foreignvisitors. (Leighton 1992:214-219) In Tuva there is a strong tradition of throat singing2, a phenomenon where the listener can heartwo different controlled tones at the same time, coming from one singer. Tuva is a small country inthe Altai mountains, where throat singing has thrived, but since throat singing nomads do not stayin one place, geographical and political borders can not show where there are throat singers andwhere there are not. (Levin 2006:71) Throat singing was traditionally used in different ways in the everyday life of nomad life aroundthe Altai mountains, from throat singing to lull a baby to sleep to throat singing to call yaks on themountains. (Pegg 2001:60) Throat singing was usually sung outside because the majority of throatsingers were herders, hunters, craftsmen and tradesmen. (Tongeren 2004:56) It was also highlytaboo of women to throat sing, “Because throat-singing makes women barren!” (Levin 2006:199) Throat singing as a phenomenon has gone from being the passtime of local nomads to thecharacteristics of internationally known tuvinians, from the shamans of the steppe to persons alloverthe world through the internet. Regional competitions in throat singing have become internationallyknown. Throat singing as a phenomenon has become known by persons who do not come fromTuva, and is being taught by persons who do not come from Tuva.1Tuva is a republic in Russia, in the South of Siberia, to the borders Northwest of Mongolia. There are 300.000persons living in Tuva, half of them live in urban areas, and the average age for a person in Tuva is 25 years old.(http://demoscope.ru/weekly/2007/0301/barom04.php 2008) There are two major ethnicities in Tuva, 77-80%Tuvans and ~20% Russians. The only other calculable group is barely 1%, the Khalkhas.(http://en.wikipedia.org/wiki/Tuva 2008)2As the locus of inquiry in this study is based on the Tuvan style of throat singing, whenever the term “throatsinging” is used it refers to tuvan style throat singing. When other styles of throat singing are mentioned, it will sayso in the text, like so “Mongolian throat singing” or so “Inuit throat singing”.1 Introductionpage 1

There are different ways of categorizing different techniques and styles3 of throat singing, somesimpler then others. Which techniques exist differs between clans and villages. The most simplecategorisation is just three different techniques. These are Kargyraa, Khoomei and Sygyt. Kargyraais the technique which creates most bass-sound, as it takes the normal singing voice down oneoctave. Sygyt is the one with highest pitch, creating an almost whistle-like sound. Khoomei is themost basic technique, having a middle-range character compared to the other two techniques.Together, these three are known as Khoomei. Khoomei is not just a sub-category, but also a wordthat describes all the techniques and styles. (Tongeren 2004:18-19)A translation of the Tuvan words also gives an insight into what technique they represent: Sygytmeans “whistle”, kargyraa means “to roar like a waterfall” or “croak like a black crow”,borbangnadyr means “rolling” and “chylandyk” is an onomatopoetic word describing the soundmade by a type of bird called chylandyk. (Pegg 2001:302, Levin 2006:67,228) The Tuvan word forthroat singing, “khoomei”, is believed to have its origin in the Mongolian word for throat orpharynx, kögemei. (Pegg 1992:31, Lundberg&Ronström 2002:13)Sometimes you can think, “ah, what clear tones that singer is producing”, but this is physicallynot true. A sound produced by a voice contains all the tones in an entire octave, with thefundamental, the lowest tone, being the one with the most volume, usually. Your voice producingapparatus is everything from your abdominal muscles to your lips, and each part of your body inyour voice producing apparatus helps shape the sound you make. In normal speech and singing, onepart, like your jaw, is responsible for shaping the volume of one formant. A formant is a resonantpeak in your voice. A resonant peak is a slightly higher volume on a few bundled harmonics. Andharmonics, in this case, are the tones in your voice that you’re not usually aware of, the tones besideyour fundamental. A specific set of resonant peaks make up the cognitive characteristics for avowel, which is why humans can understand each other even though they have different voices.(Tongeren2004:11-18)3A shared definition on the difference between “styles” and “techniques” within throat singing doesn’t exist. In caseswhere there has to be definition on this, this on is used: Techniques are based on larger physical changes while stylesare personal preferences. As an example: Singing high-pitched and with a faster rythm is a style. Applying increasedconstriction in the throat to make the ventricular folds vibrate is a technique.1 Introductionpage 2Illustration 1: An example of how a tuvan (EmiC) taxonomyof throatsinging can look like,using tuvan words to describe tuvan techniques.Made by the author.KhoomeiBorbangnadyrSygytChylandykKargyraaKhoomei

In throat singing and overtone singing, you combine formants to increase the volume of certainharmonics, to make the overtones more audible. A metaphor that works here is that high4 formantsequals audible overtones. (Lundberg&Ronström 2002:15) But throat singing is primarily asubjective experience, for both the listener and the singer. If you can not distinguish two differenttones coming from one singer, then it is just ordinary singing. This is so even in Tuva, where theylike to focus on the timbre of the voice. (Levin 2006:47-48) Timbre, or colour, being the relationbetween the harmonics.In throat singing, but not in overtone singing, you constrict the airflow trough your throat.(Tongeren 2004:23) This is the basis for tuvan style throat singing, khoomei. If you apply tremoloto your tongue root while singing khoomei, you get the technique borbangnadyr instead ofkhoomei. If you put your tongue tip to the roof of your mouth when singing khoomei, you get thebasic technique sygyt. Sygyt is hard to do, it requires alot of throat constriction and air pressure.(Lundberg&Ronström 2002:15)Illustration 2: Tree arrangement of throat singing, made by the author,using early cognitive anthropology as reference. (Tyler 2004:402)Plus (+) indicates presence of feature,minus (-) indicates absence of feature.VVF is short for Vocal-Ventricular Folds.Kargyraa uses a special kind of vibration of the vocal-ventricular folds, they vibrate half the speedof the normal vocal folds, making the voice drop an entire octave. The vocal-ventricular folds(VVF), sometimes also referred to as false vocal folds, are located above the normal vocal folds. Inall kinds of tuvan throat singing, the VVFs are involved in one way or another, but in kargyraa theymake the voice sound really low. (Sakakibara et al. 2002, Fuks et al. 1998:57-58) This is also how4“High” here meaning both pitch as well as volume.1 Introductionpage 3More then one tone audibleNormal singingThroat constrictionWesternOvertone singing-+VVF’s vibratinghalf the speed of vocal folds+–Sygyt+-+KargyraaChylandyk-+Lip tremoloKhoomeiBorbangnadyrTip of tonguetouching palate-+ByrlangTonguetremolo-+Fast VVF vibrations & Tip of tonguetouching palate

Description
This investigation describes various characteristics of a particular phonation mode, vocal-ventricular mode (VVM), as produced by a healthy, musically-trained subject. This phonation mode was judged as perceptually identical to that used in the Tibetan chant tradition. VVM covered a range close to an octave, starting at about 50 Hz. High-speed glottography revealed that the ventricular folds oscillated at half the frequency of the vocal folds thus yielding a frequency of f/2. Phonation at f/3 was also possible. Presumably, aerodynamic forces produced by the glottal flow pulses sustained the vibrations of the ventricular folds. Complementary aspects of this type of phonation were compared to phonation in modal and pulse registers by acoustical analysis of the audio signal, by inverse filtering of the flow signal and by electroglottography (EGG). In addition, oesophageal pressures were measured. These analyses …

Dans cet atelier (en anglais), Johan Sundberg présente une revue de ses recherches menées sur la technique vocale des chanteurs. The talk presents examples of investigations which have aimed at understanding the vocal technique of singers. The relevance of voice research to vocal pedagogy is discussed in the light of examples of alternative facts that are still surviving among some teachers of singing. A variety of studies of the singing voice are reviewed and the advantage of analysing singers’ as opposed to untrained voices’ vocal characteristics will be discussed. Also some studies of aesthetical and expressive aspects of singing are discussed.

Perceptual aspects of singing*

Summary

The relations between acoustic and perceived characteristics ofvowel sounds are demonstrated with respect to timbre, loudness, pitch, and expressive time patterns. The conditions for perceiving an ensemble of sine tones as one tone or several tones are reviewed. There are two aspects of timbre of voice sounds: vowel quality and voice quality. Although vowel quality depends mainly on the frequencies of the lowest two formants, voice quality depends mainly on the frequencies of the higher formants. In particular, the center frequency of the so-called singer’s formant seems perceptually relevant. Vocal loudness, generally assumed to correspond closely to the sound pressure level, depends rather on the amplitude balance between the lower and the higher spectrum partials. The perceived pitch corresponds to the fundamental frequency, or for vibrato tones, the mean of this frequency. In rapid passages, such as coloratura singing, special patterns are used. Pitch and duration differences are categorically perceived in music. This means that small variations in tuning or duration do not affect the musical interval and the note value perceived. Categorical perception is used extensively in music performance for the purpose of musical expression because without violating the score, the singer may sharpen or flatten and lengthen or shorten the tones, thereby creating musical expression.
