The flute is a family of musical instruments in the woodwind group. Unlike woodwind instruments with reeds, a flute is an aerophone or reedless wind instrument that produces its sound from the flow of air across an opening. According to the instrument classification of Hornbostel–Sachs, flutes are categorized as edge-blown aerophones.
A musician who plays the flute can be referred to as a flute player, flautist, flutist or, less commonly, fluter or flutenist.
Flutes are the earliest extant musical instruments. A number of flutes dating to about 43,000 to 35,000 years ago have been found in the Swabian Jura region of present-day Germany. These flutes demonstrate that a developed musical tradition existed from the earliest period of modern human presence in Europe. Flutes, including the famous Bansuri, have been an integral part of Indian classical music since 1500 BC. A major deity of Hinduism, Krishna, has been associated with the flute.
The word flute first entered the English language during the Middle English period, as floute, or else flowte, flo(y)te, possibly from Old French flaute and from Old Provençal flaüt, or else from Old French fleüte, flaüte, flahute via Middle High German floite or Dutch fluit. The English verb flout has the same linguistic root, and the modern Dutch verb fluiten still shares the two meanings. Attempts to trace the word back to the Latin flare (to blow, inflate) have been pronounced "phonologically impossible" or "inadmissable". The first known use of the word flute was in the 14th century. According to the Oxford English Dictionary, this was in Geoffrey Chaucer's The Hous of Fame, c.1380.
