Overtone singing (also known as Throat singing) is a fascinating method of singing where the singer is able to manipulate the harmonic resonance created from the air traveling from the lungs past the vocal cords to produce a melody. Talented overtone singers have the ability to produce from two to four different notes at the same time!
Kongar-ol Ondar, is one such person who can do this and has garnered much international attention and fans. Hailing from Tuva (a small protectorate of Russia) Kongar-ol sings a brand of overtone singing that is aptly known as Tuvan.
A fascinating fact arose when researching about this topic in that overtone singing seems to be known and practiced by many cultures around the World for centuries! For example one such people are the Inuit of Canada who have a style called Katajjaq which is facing a resurgence in popularity.
