Piccolo trumpet

The smallest of the trumpet family is the piccolo trumpet, 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.
