 Traditionally, New Orleans brass bands could feature various instrumentations, often including trumpets, trombones, clarinets, saxophones, sousaphones, and percussion.The music played by these groups was often a fusion between European-styled military band music and African folk music brought to the Americas by West African slaves and the idiom played a significant role in the development of traditional jazz.Early brass bands include the Eureka Brass Band, the Onward Brass Band, the Excelsior Brass Band, the Tuxedo Brass Band, the Young Tuxedo Brass Band, the Camelia Brass Band, and the Olympia Brass Band.
