The Singing Sergeants, the official chorus of the United States Air Force, is one of the world's most versatile and traveled choral organizations. Originally formed in 1945 from within the ranks of The United States Air Force Band, the chorus is now composed entirely of professional vocalists from leading colleges, universities and music conservatories throughout the world; and who are all sergeants in the United States Air Force. The Singing Sergeants have appeared before every chief executive of the United States since President Truman, as well as with the New York Philharmonic; the Philadelphia, Cleveland, Houston and National Symphony Orchestras; and both the Boston and Cincinnati Pops. The group has performed at White House, State Department, Supreme Court, Congressional, Department of Defense and high-level civilian functions. Additionally, an important part of the chorus' performing schedule is supporting the president and vice president of the United States, as well as top government and military officials. Presenting the music of America to the people of the world, the chorus has appeared before millions of people in live performances and countless more on radio and television programs. The Singing Sergeants have performed in all 50 states and 49 countries, including a historic trip to the People's Republic of China. It is through these goodwill tours that the Singing Sergeants bring the people of America and the world together.
