Trumpet

A trumpet is a musical instrument. It has the highest register in the brass family. As a signaling device in battle or hunting, trumpets have a very long history, dating back to at least 1500 BC; they have been used as musical instruments since the 15th century. Trumpets are used in art music styles, where they are an instrument in the orchestra and in concert bands, and in popular music styles such as jazz. They are played by blowing air through almost-closed lips, producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century they have primarily been constructed of brass tubing, usually bent twice into a rounded oblong shape.

There are several types of trumpet. The most common is a transposing instrument pitched in B♭ with a tubing length of about 1.48 m (4 ft 10 in). Earlier trumpets did not have valves, but modern instruments generally have either three piston valves or, more rarely, three rotary valves. The use of rotary valve trumpets is more commonly seen in European countries, particularly Germany and Austria. Each valve increases the length of tubing when engaged, thereby lowering the pitch.

A musician who plays the trumpet is called a trumpet player or trumpeter.
