Flute
A Brief History of the Flute 
Except for percussion, the flute is arguably the oldest musical instrument known, and ancient examples have been found all over the world. Unlike the modern side-blown (cross or transverse) instrument, early flutes were end-blown (vertical) and were made of animal bones, such as a reindeer horn or sheep's tibia, pierced with a blow-hole and several finger-holes.
The transverse flute is believed to have been used for the first time in the orchestra in 1681, in one of Lully's ballets for the French court. By 1691 the flute had entered the French Royal Chapel band, and over the next 50 years, coupled with the advent of public concerts in France, Germany and England, it became an indespensable member of the orchestra.
Always a difficult instrument to master, many people have tried to improve the mechanics of the flute. One of its more important modifiers was Theobald Boehm (1794 - 1881), a flautist from Munich, who in the 1830s introduced a large-holed instrument that overcame the acoustic deficiencies inherent in earlier flutes. Boehm's changes were revolutionary inasmuch as they changed the closed keys into open keys controlled by rings. By 1847 he had increased the size of the tone-holes so much that they had to be closed by padded covers, worked by keys that both operated independently and interacted with others, and it is this type of flute that is played today.
