The bansuri (Hindi: बांसुरी,Nepali: बाँसुरी, Marathi: बासरी Assamese: বাঁহি, Bengali: বাঁশি) is a transverse alto flute of Bangladesh, India and Nepal made from a single hollow shaft of bamboo with six or seven finger holes. An ancient musical instrument associated with cowherds and the pastoral tradition, it is intimately linked to the love story of Krishna and Radha, and is depicted in Buddhist paintings from around 100 AD. The Bansuri is revered as Lord Krishna's divine instrument, and is often associated with Krishna's Rasa lila; mythological accounts tell of the tunes of Krishna's flute having a spellbinding and enthralling effect not only on the women of the Braj, but even on the animals of the region. The North Indian bansuri, typically about 14 inches in length, was traditionally used as a soprano instrument primarily for accompaniment in lighter compositions including film music. The bass variety (approximately 30", tonic E3 at A440Hz), pioneered by Pt. Pannalal Ghosh and elevated to heights of global renown by the brilliance of Pt. Hariprasad Chaurasia has now been indispensable in Hindustani Classical music for well over half a century. Bansuris range in size from less than 12" to nearly 40".

The word bansuri originates in the Sanskrit bans [bamboo] + swar [musical note]. There are two varieties of bansuri: transverse, and fipple. The fipple flute is usually played in folk music and is held at the lips like a whistle. Because it enables superior control, variations and embellishments, the transverse variety is preferred in Indian classical music.
Pandit Pannalal Ghosh (1911–1960) elevated the Bansuri from a folk instrument to the stage of serious classical music.[1] He experimented with the length, bore and number of holes, and found that longer length and larger bore allowed for better coverage of the lower octaves. He eventually pioneered longer bansuris with larger bores and a seventh hole placed a quarter turn inwards from the line of the other six finger holes.
Bansuri construction is a complex art. The bamboo suitable for making a bansuri needs to possess several qualities. It must be thin walled and straight with a uniform circular cross section and long internodes. Being a natural material, it is difficult to find bamboo shafts with all these characteristics, which in turn makes good bansuris rare and expensive. Suitable species of bamboo (such as Pseudostachyum) with these traits are endemic to the forests of Assam and Kerala.[2]
After harvesting a suitable specimen, the bamboo is seasoned to allow naturally present resins to strengthen it. Once ready, a cork stopper is inserted to block one end, next to which the blowing hole is burnt in. The holes must be burnt in with red hot skewers since drilling causes the fibrous bamboo to split along the length, rendering it useless. The approximate positions of the finger holes are calculated by measuring the bamboo shaft's inner and outer diameters and applying certain formulae. Flute makers have only one chance to burn the holes, and a single mistake ruins the flute, so they usually begin by burning in a small hole, after which they play the note and using a chromatic tuner, gradually make adjustments by sanding the holes in small increments. Once all the holes are perfected, the bansuri is steeped in a solution of antiseptic oils, after which it is cleaned, dried and its ends are bound with silk or nylon threads for both decoration as well as protection against thermal expansion.
Bansuris range in length from less than 12 inches (called muralis) up to about 40 inches (shankha bansuris). 20-inch bansuris are common. Another common and similar Indian flute played in South India is the venu, which is shorter in length and has 8 finger holes(This type of Indian flute is played by the famous Carnatic Musician Shashank Subramanyam). The index, middle, and ring fingers of both hands are usually used to finger the six hole bansuri. For the seven hole bansuri, the little finger (pinky) of the lower hand is usually employed.[3]
The sound of a bansuri is generated from resonance of the air column inside it. The length of this column is varied by closing or leaving open, a varying number of holes. Half-holing is employed to play flat or minor notes. The 'sa' (on the Indian sargam scale, or equivalent 'do' on the octave) note is obtained by covering the first three holes from the blowing-hole. Octaves are varied by manipulating one's embouchure and controlling the blowing strength. Various grip styles are used by flutists to suit different lengths of Bansuris, the two prominent styles being the Pannalal Ghosh grip, which uses the fingertips to close the holes, and the Hariprasad Chaurasia grip, which uses the pads(flat undersides) of the fingers to close the holes.[4] While playing, the sitting posture is also important in that one should be careful not to strain one's back over long hours of practice. The size of a Bansuri affects its pitch. Longer bansuris with a larger bore have a lower pitch and the slimmer and shorter ones sound higher.
In order to play the diatonic scale on a bansuri, one needs to find where the notes lie. For example, in a bansuri where Sa or the tonic is always played by closing the first three holes, is equivalent to D, one can play sheet music by creating a finger notation that corresponds to different notes. A flutist is able to perform complex facets of Raga music such as microtonal inflections, ornamentation, and glissando by varying the breath, performing fast and dextrous fingering, and closing/opening the holes with slow, sweeping gestures. These techniques are demonstrated by the famous Indian flautist Pt. Hariprasad Chaurasia.
Since, Bansuri is a natural woodwind instrument, it is prone to cracks and thermal stresses while playing.
Famous masters of the bansuri include Pt. Pannalal Ghosh, Pt. Bholanath Prasanna, Pt. Hariprasad Chaurasia, Pt. Rajendra Prasanna, Vijay Raghav Rao, Pt. Devendra Murdeshwar, Pt. Raghunath Seth, Ronu Majumdar and Nityanand Haldipur, Pravin Godkhindi
