The 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, which is pitched one octave below the standard B♭ or C Trumpet.
Trumpet-like instruments have historically been used as signalling devices in battle or hunting, with examples dating back to at least 1500 BCE. They began to be used as musical instruments only in the late 14th or early 15th century. Trumpets are used in art music styles, for instance in orchestras, concert bands, and jazz ensembles, as well as in popular music. They are played by blowing air through nearly-closed lips, producing a "buzzing" sound that starts a standing wave vibration in the air column inside the instrument. Since the late 15th century, trumpets have primarily been constructed of brass tubing, usually bent twice into a rounded rectangular shape.
There are many distinct types of trumpet, with the most common being pitched in B♭, having a tubing length of about 1.48 m.
