Overview

The trumpet is the musical instrument with the highest register in the brass family. Trumpets are among the oldest musical instruments,[1] dating back to at least 1500 BCE. They are constructed of brass tubing bent twice into an oblong shape, and are played by blowing air through closed lips, producing a "buzzing" sound which starts a standing wave vibration in the air column inside the trumpet. There are several types of trumpet; the most common is a transposing instrument pitched in B♭. The tube length of the most common B-trumpet is about 134 cm. The predecessors to trumpets did not have valves, but modern trumpets have either three piston valves or three rotary valves. Each valve increases the length of tubing when engaged, thereby lowering the pitch. The trumpet is used in many forms of music, including classical music and jazz. A musician who plays the trumpet is called a trumpet player or trumpeter. The most common type is the B♭ trumpet, but low F, C, D, E♭, E, G and A trumpets are also available. The C trumpet is most common in American orchestral playing, where it is used alongside the B♭ trumpet. Its slightly smaller size gives it a brighter, more lively sound. Because music written for early trumpets required the use of a different trumpet for each key — they did not have valves and therefore were not chromatic — and also because a player may choose to play a particular passage on a different trumpet from the one indicated on the written music, orchestra trumpet players are generally adept at transposing music at sight, sometimes playing music written for the B♭ trumpet on the C trumpet, and vice versa.
