The United States Air Force Band is an American military ensemble formed in Washington, D.C., in 1941 to provide musical support for the United States Air Force, performing concert band, ceremonial, chamber and jazz repertoire. Its activities include state and ceremonial performances, public concerts, educational outreach and international tours, and its repertoire ranges from traditional military and wind-band works to arrangements of popular and contemporary music, reflecting an evolution from primarily ceremonial duties to a broader public-facing musical role.
