While it is not known when the flute was invented, in the Western culture, depictions of the flute date as far as the 10th century, according to FluteHistory.com. Theobald Boehm developed a modern version of the flute.
Between 1832 and 1847, Boehm worked on creating an improved model of the flute, which is still used in modern times, although minor changes to his model have been made. The flute type that he produced featured a parabolic head joint, open-standing keys and finger pads.
While playing the flute, the musician blows into a sharp edge, which causes the air that remains enclosed in the tube to vibrate and produce various sounds.
