The Jazz Band is an auditioned traditional big band consisting of saxophones, trumpets, trombones, and a rhythm section. The band performs traditional jazz, Latin, and rock music from the 1920s to the modern era. Jazz band begins in early January and meets twice a week after school. The band performs at most school concerts, as well as several area jazz festivals. Performances will be announced at least three weeks in advance. Membership in this group is by audition.

Some years, a second group, the Jazz Orchestra, is offered as a “lab” group designed to let students explore jazz music and new instruments in a low-key, supportive environment. This group allows students who play non-traditional jazz instruments to learn a new instrument so they can audition for jazz band if they choose. Typically, clarinet players learn saxophone; horn players learn trumpet; and euphonium or tuba players learn trombone. This group meets once a week during the spring semester and is open to all Willow Spring High School students.
