A brass band is a musical ensemble that features brass and percussion instruments. Synonyms for a brass band include a brass ensemble, a brass orchestra, or a brass group. Some may refer to it as a brass quintet, which typically means five performers in the group. A marching band could also be considered a brass band if they feature primarily brass and percussion instruments, such as trumpets, trombones, and drums. The term brass choir is also occasionally used, particularly when the group is focused on classical repertoire. Ultimately, the name given to a brass band is often determined by the specific lineup and repertoire of the group.
