Tibetan Overtone Chant

Tibetan overtone chanting, sometimes loosely called throat singing though distinct from the Central Asian tradition of that name, is a vocal technique in which a single singer produces two or more audible pitches simultaneously, a low fundamental drone and one or more higher overtones shaped and amplified by careful control of the mouth, throat and vocal tract.

Practiced most distinctively within certain Tibetan Buddhist monastic lineages, particularly in ritual chanting associated with the Gyuto and Gyume tantric colleges, the technique produces an unusually deep, resonant fundamental tone, achieved partly through specialized vocal training and partly through a chanting register pitched well below a singer's ordinary speaking voice, over which a second, higher tone can be heard as a distinct melodic line seemingly independent of the drone beneath it. The chant is used specifically within tantric ritual contexts, accompanying the recitation of particular texts and prayers, and monks trained in the technique typically undergo years of specialized vocal practice to develop and sustain it, since producing a clear, stable overtone over an equally stable low fundamental for extended ritual passages requires considerable control that is not part of ordinary monastic chant training more broadly.

Within its home ritual context, Tibetan overtone chanting is not performed as a standalone musical event but as one element of extended tantric liturgical practice, typically accompanying deep-voiced group recitation of specific texts during pujas and other ceremonies conducted by monks trained in the technique, often alongside long horns, drums and cymbals that together produce the distinctive low, resonant soundscape associated with Tibetan monastic ritual more broadly. The chanting style is closely associated with specific monastic institutions and lineages, notably the Gyuto and Gyume tantric colleges, whose monks have historically been recognized within the wider Tibetan Buddhist world as specialists in the technique, and formal training in the chant is generally embedded within a monk's broader tantric and liturgical education rather than taught as an isolated vocal skill.

Since the mid twentieth century, following the Tibetan diaspora after 1959, recordings and international concert tours by monks from these institutions introduced Tibetan overtone chanting to audiences well beyond its traditional monastic setting, and the technique has since become one of the more widely recognized examples of Tibetan Buddhist ritual sound internationally, sometimes performed in secular concert settings that necessarily present the chant apart from the specific tantric liturgical context in which it is traditionally embedded.
