How a single voice can sing two notes at once

In short: It sounds like a supernatural feat: one singer, yet two distinct pitches vibrating simultaneously. This is the art of throat-singing, a complex vocal mastery where musicians manipulate their anatomy to amplify harmonics, creating melodies that float above a deep, steady drone.

Originating among the Turko-Mongol tribes of the Altai and Sayan mountains, throat-singing is a sophisticated physiological feat. Unlike standard singing, the practitioner uses sustained, pressurized airflow from the chest and stomach to manipulate the resonating chambers of the vocal tract. By activating specific muscle combinations, the singer reinforces harmonics—both overtones and undertones—to produce multiple pitches at once. While Western scholars historically called this 'overtone-singing,' the term 'throat-singing' was adopted to reflect the presence of harmonics below the fundamental drone in guttural styles, as well as the Mongolian term höömei.

The tradition is deeply rooted in the landscapes of Inner Asia, spanning parts of Mongolia, Russia, and China. In these nomadic and semi-nomadic communities, the music serves as a bridge to the natural and supernatural worlds, used to summon spirits, lull infants, or even mimic the sound of horse riders' stirrups. The Tyvan people have developed the practice extensively, with styles like sygyt producing whistle-like melodies and kargyraa offering a low, growling texture. Other regional variations, such as those in western Mongolia, are even classified by which part of the body—like the tongue, lips, or chest—is used to shape the sound.

The history of the art is one of both suppression and revival. During the first half of the 20th century, communist regimes in Russia and Mongolia prohibited the practice, labeling it a 'backward' ritual. However, following the dissolution of these governments in the early 1990s, the tradition was re-established as a national art form. Today, while the practice remains a pillar of ethnic identity, it has also entered the global commercial realm, with contemporary musicians blending these ancient techniques with rock, pop, and independent genres.
