High Quality Content by WIKIPEDIA articles! The pocket trumpet is a compact size B? trumpet, with the same playing range as the regular trumpet. It is a non-standard instrument, not to be found in orchestral brass sections and is generally regarded as a novelty. The tubing is wound more tightly than that of a standard trumpet to reduce its size while retaining the instrument's range. It is used mostly by trumpet players as a practice instrument, something they can pack in a suitcase and take with them when their standard trumpets would be awkward to carry. Although not having a reputation as a serious orchestral instrument, it has occasionally been used in jazz or other ensembles to add flair and variety. The concept of reducing the brass instrument size without reducing the resonating tube length can be seen in several 19th century models of cornet. Pocket cornets have been constructed since the 1860s, supposedly used in marching bands.
