The bansuri (Hindi: बांसुरी);(Bangla: বাঁসুরী) is a transverse alto flute of India, Pakistan, Bangladesh, and Nepal, made of a lone stick of bamboo with six or seven open 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. It is intimately associated with Krishna's Rasa lila; the tunes on his flute are poetically associated with driving the women of Braj mad. The North Indian bansuri, typically about 14 inches, was traditionally used as a soprano instrument primarily for accompaniment in lighter compositions including film music. There are many size of bansuri from 14" to 30".

A wind instrument is a musical instrument that contains some type of resonator (usually a tube), in which a column of air is set into vibration by the player blowing into (or over) a mouthpiece set at the end of the resonator. The pitch of the vibration is determined by the length of the tube and by manual modifications of the effective length of the vibrating column of air. In the case of some wind instruments, sound is produced by blowing through a reed; others require buzzing into a metal mouthpiece.

A musical instrument is constructed or used for the purpose of making the sounds of music. In principle, anything that produces sound can serve as a musical instrument. The history of musical instruments dates back to the beginnings of human culture. The academic study of musical instruments is called organology.

The date and origin of the first device of disputed status as a musical instrument dates back as far as 67,000 years old; artifacts commonly accepted to be early flutes date back as far as about 37,000 years old. However, most historians believe determining a specific time of musical instrument invention to be impossible due to the subjectivity of the definition.

Musical instruments developed independently in many populated regions of the world. However, contact among civilizations resulted in the rapid spread and adaptation of most instruments in places far from their origin. By the Middle Ages, instruments from Mesopotamia could be found in the Malay Archipelago and Europeans were playing instruments from North Africa. Development in the Americas occurred at a slower pace, but cultures of North, Central, and South America shared musical instruments.
