Throat singer

Overtone singing—also known as overtone chanting, harmonic singing or throat singing—is a type of singing in which the singer manipulates the resonances (or formants) created as air travels from the lungs, past the vocal folds, and out of the lips to produce a melody.

The harmonics (fundamental and overtones) of a sound wave made by the human voice can be selectively amplified by changing the shape of the resonant cavities of the mouth, larynx and pharynx. This resonant tuning allows singers to create apparently more than one pitch at the same time (the fundamental and a selected overtone), while actually generating only a single fundamental frequency with their vocal folds.

Each note is like a rainbow of sound. When you shoot a light beam through a prism, you get a rainbow. You think of a rainbow of sounds when you sing one note. If you can use your throat as a prism, you can expose the rainbow - through positioning the throat in a certain physical way, which will reveal the harmonic series note by note.

It is thought that the art of overtone singing originated from south western Mongolia in today's Khovd Province and Govi Altai region. Nowadays, overtone singing is found throughout the country and Mongolia is often considered the most active place of overtone singing in the world. The most commonly practiced style, Khöömii (written in Cyrillic as Хөөмий), can be divided up into the following categories:

Mongolians also sing many other styles such as "karkhiraa" (literally "growling") and "isgeree".

Many of these styles are also practiced around neighboring regions such as Tuva and Altai.

Tuvan overtone singing is practiced by the Tuva people of southern Siberia, Russia. The history of Tuvan overtone singing reaches far back in local history. There is a wide range of vocalizations, including Sygyt, Kargyraa (which also uses a second sound source), Khoomei, Chylandyk, Dumchuktaar, and Ezengileer. Most of these styles are closely related to the styles and variations in neighboring Mongolia.
