Flute

The flute is a musical instrument of 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 or embouchure.

The oldest flute ever discovered, though this is disputed, may be a fragment of the femur of a juvenile cave bear, with two to four holes, found at Divje Babe in Slovenia and dated to about 43,000 years ago. In 2008 another flute dated back to at least 35,000 years ago was discovered in Hohle Fels cave near Ulm, Germany. The five-holed flute has a V-shaped mouthpiece and is made from a vulture wing bone. The researchers involved in the discovery officially published their findings in the journal Nature, in June 2009.[4] The discovery is also the oldest confirmed find of any musical instrument in history.

A three-holed flute, 18.7 cm long, made from a mammoth tusk (from the Geißenklösterle cave, near Ulm, in the southern German Swabian Alb and dated to 30,000 to 37,000 years ago)[8] was discovered in 2004, and two flutes made from swan bones excavated a decade earlier (from the same cave in Germany, dated to circa 36,000 years ago) are among the oldest known musical instruments.
