A bansuri is an ancient side blown flute originating from India and Nepal. It is an aerophone produced from bamboo and metal like material used in many nepali lok songs. A bansuri is traditionally made from a single hollow shaft of bamboo with seven finger holes. Some modern designs come in ivory, fiberglass and various metals. The six hole instrument covers two and a half octaves of music. The bansuri is typically between and in length, and the thickness of a human thumb. One end is closed, and few centimeters from the closed end is its blow hole. Longer bansuris feature deeper tones and lower pitches. The traditional design features no mechanical keys, and the musician creates the notes they want by covering and uncovering the various finger holes. The bansuri-like flute is depicted in ancient Buddhist, Hindu and Jain temple paintings and reliefs, and is common in the iconography of the Hindu god Krishna. it is intimately linked to the love story of Krishna and Radha. The bansuri is revered as Lord Krishna's divine instrument and is often associated with Krishna's Rasa lila dance. These legends sometimes use alternate names for this wind instrument, such as the murali. However, the instrument is also common among other traditions such as Shaivism. The early medieval Indian texts also refer to it as vaṃśi, while in medieval Indonesian Hindu and Buddhist arts, as well as temple carvings in Java and Bali dated to be from pre-10th century period, this transverse flute has been called wangsi or bangsi. There are many origins of bansuri but the word bansuri itself is a Nepali word and is a traditionally used musical instrument of Nepal. Bansuri is an musical instrument mostly used in Nepal, according to various religious books Lord Krishna used muralie not bansuri so it is very important to know the difference between bansuri and muralie The word bansuri originates in the bans (बाँस) [bamboo] + sur (सुर) [melody]. A phonetically similar name for the same instrument, in early medieval texts, is the Sanskrit word vaṃśi which is derived from root vaṃśa (Sanskrit: वंश) meaning bamboo.
