Khöömei is the Mongolian art of shaping a continuous vocal tone so that selected overtones become clearly audible. Listeners often perceive two layers at once: a low drone and a narrow, flute-like melody floating above it. The effect is acoustic skill, not electronic processing and not two independent voices.
The tradition is strongly associated with western Mongolia and the Altai, while related overtone-singing practices are found across Inner Asia. Mongolian performers use several techniques, names and regional styles; the familiar English label “throat singing” is useful but broad.
How khöömei works
Every sustained vocal note contains a fundamental frequency and higher partials. In ordinary speech and song these partials blend into tone colour. A khöömei singer carefully adjusts the tongue, lips, jaw and vocal tract to amplify one overtone at a time. Moving that resonant focus creates the high melody while the fundamental continues underneath.
Breath support is controlled and the posture is stable. Skilled sound may feel powerful to the listener, but it is not produced by simply squeezing the throat as hard as possible.
What does the word khöömei mean?
The term is associated with the throat or pharyngeal area. Spellings in English include khöömei, khoomei, höömii and xöömij because Mongolian and regional names are transliterated through different systems.
Two widely discussed sound families
Kharkhiraa
Kharkhiraa is characterized by a deep, rumbling foundation. The sound can involve vibration above and below the ordinary sung pitch, creating a dark texture. Performers may also articulate a higher overtone melody over it.
Isgeree khöömei
Isgeree means whistling. In this approach, high overtones are sharply focused so they resemble a whistle above the drone. Tongue and lip position guide the melody.
These labels do not capture the whole tradition. Performers also describe techniques associated with the nose, chest, palate, throat, echo and syllabic articulation, and terminology can differ among teachers.
Khöömei and the landscape
Musicians and communities connect khöömei with the sounds of wind, water, mountains and animals. This should not be reduced to a claim that one person “invented” the technique by copying a waterfall. The more important point is a tradition of attentive listening in a pastoral environment and the cultural value placed on resonance.
UNESCO recognition
The Mongolian traditional art of khöömei was inscribed on UNESCO’s Representative List of the Intangible Cultural Heritage of Humanity in 2010. A related Chinese nomination for Mongolian art of singing, Khoomei, was inscribed in 2009. These listings recognize living communities and transmission; they do not turn the art into the property of a single commercial performer.
Khöömei, sygyt and overtone singing
English-language discussions sometimes mix Mongolian and Tuvan labels. Sygyt, for example, is a Tuvan term often used for a high whistle-like style. The sounds may be compared, but respectful writing keeps community-specific terminology clear rather than treating Central Asian traditions as interchangeable.
How to listen
- Find the steady low pitch beneath the sound.
- Listen for a narrow overtone that moves like a separate melody.
- Notice changes in vowels and mouth shape.
- Compare solo singing with khöömei combined with morin khuur, tovshuur or tsuur.
- Listen to multiple performers; there is no single correct timbre.
Can you learn khöömei safely?
Yes, but instruction matters. Stop if you feel pain, burning, dizziness or persistent hoarseness. A qualified teacher can help develop resonance without excessive force. Online demonstrations are useful for listening, but they cannot monitor tension or vocal health.

Frequently asked questions
Is khöömei the same as singing two notes?
The listener hears a fundamental and a selected overtone, but both belong to one complex vocal sound.
Is khöömei only performed by men?
No. Men have often dominated public performance histories, but women also learn and perform overtone singing.
Does it damage the voice?
Well-taught technique should not cause pain. Forcing unfamiliar constriction can cause strain, so beginners should learn gradually.
Khöömei becomes most intelligible when heard as both acoustics and culture: a precise manipulation of resonance carried through teachers, families, landscapes and contemporary stages.
