TromboneThe trombone (Posaune, Italian, French: trombone) is a musical instrument in the brass family. As with all brass instruments, sound is produced when the player's vibrating lips cause the air column inside the instrument to vibrate. Nearly all trombones use a telescoping slide mechanism to alter the pitch instead of the valves used by other brass instruments. The valve trombone is an exception, using three valves similar to those on a trumpet, and the superbone has valves and a slide.
OrchestraAn orchestra (ˈɔːrkɪstrə; ) is a large instrumental ensemble typical of classical music, which combines instruments from different families. There are typically four main sections of instruments: bowed string instruments, such as the violin, viola, cello, and double bass woodwinds, such as the flute, oboe, clarinet, and bassoon brass instruments, such as the horn, trumpet, trombone, cornet, and tuba percussion instruments, such as the timpani, snare drum, bass drum, cymbals, triangle, tambourine, and mallet percussion instruments Other instruments such as the piano, harpsichord, and celesta may sometimes appear in a fifth keyboard section or may stand alone as soloist instruments, as may the concert harp and, for performances of some modern compositions, electronic instruments, and guitars.
TrumpetThe trumpet is a brass instrument commonly used in classical and jazz ensembles. The trumpet group ranges from the piccolo trumpet—with the highest register in the brass family—to the bass trumpet, pitched one octave below the standard B or C trumpet. Trumpet-like instruments have historically been used as signaling devices in battle or hunting, with examples dating back to at least 2000 BC. They began to be used as musical instruments only in the late 14th or early 15th century.
