The Limbe is a side-blown wind instrument, mostly made of hard wood or bamboo. It is considered as one of the valuable traditional musical instruments among Mongolians for its unique technique and characteristics such as hidden tune associated with circular breathing, and its performing techniques of skilful and delicate movements of fingers and tongue. The "Circular breathing" is a great achievement of nomadic Mongolians derived from their creativity, result of the exploration and necessity of their daily life. The origin and development of circular breathing is closely bound up with the skills and knowledge of ancient craftsmen or metalsmiths who specialized in gold and silver. Early Mongolian craftsmen used circular breathing techniques for crafting various decorative and ornamental items including valuable jewelleries.
