The capabilities of a human body are sometimes beyond the brain’s imagination. For example, it’s hard for most people to believe the sound in the video above came from a human being rather than an instrument. That is because the singer is able to produce a continuous bass and simultaneously produce one or more pitches through his/her throat. This unique way of singing is known as khoomei, or hooliin chor (throat singing), an art of singing practiced by Mongolian communities in Inner Mongolia in northern China, Mongolia and the Russian republic of Tuva. It is also known as Tuvan throat singing in other cultures. It is believed that Khoomei could be traced back to the Huns, the nomadic people living between the 4th and 6th centuries in Central Asia and Eastern Europe. Mongolians in ancient times imitated the sound of nature, such as waterfalls, forests and animals, during nomadism and hunting as a way of connecting and showing respect. This singing art was officially inscribed on the List of Intangible Cultural Heritage by UNESCO in 2009.
