A brass band is a musical ensemble generally consisting primarily of brass instruments, most often with a percussion section. Ensembles that include brass and woodwind instruments can in certain traditions also be termed brass bands, but may be more correctly termed military bands, concert bands, or "brass and reed" bands.
