The Limbe (Mongolian: лимбэ) is a western concert flute with six finger holes from Mongolian folk music, which belongs to the nomadic pastoral culture and is usually played with circular breathing by experienced players. The continuous playing of the flute to accompany "long songs" (urtin duu) lasting up to 25 minutes was added to the UNESCO Intangible Cultural Heritage Lists in urgent need of preservation in 2011. Like most other Mongolian musical instruments, the limbe is traditionally only allowed to be played by men. The origin of the East Asian flutes such as the limbe and the related dizi in China could be traced back to the 1st millennium BC.
