The piccolo trumpet is the smallest member of the trumpet family, pitched one octave higher than the standard B♭ trumpet. Most piccolo trumpets are built to play in either B♭ or A, using a separate leadpipe for each key. The tubing in the B♭ piccolo trumpet is one-half the length of that in a standard B♭ trumpet. Piccolo trumpets in G, F, and even high C are also manufactured, but are rarer.

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, pitched one octave below the standard B♭ or C trumpet.
