The John F. Kennedy Center for the Performing Arts, commonly known as the Kennedy Center, is the national cultural center of the United States, serving as a "living memorial" to John F. Kennedy. It is located on the eastern bank of the Potomac River in Washington, D.C. Opened on September 8, 1971, the center hosts many different genres of performance art, such as theater, ballet, modern dance, classical music, jazz, pop, psychedelic, and folk music. It is the official residence of the National Symphony Orchestra and the Washington National Opera. Authorized by the National Cultural Center Act of 1958, which requires that its programming be sustained through private funds, the center represents a public–private partnership. Its activities include educational and outreach initiatives, almost entirely funded through ticket sales and gifts from individuals, corporations, and private foundations.
