Washington, D.C., formally the District of Columbia and commonly referred to as Washington; D.C.; or the district, is the capital of the United States. Founded after the American Revolution as the seat of government of the newly independent country, Washington was named after George Washington, the first president of the United States and a Founding Father. As the seat of the United States federal government and several international organizations, Washington is an important world political capital. The city, located on the Potomac River bordering Maryland and Virginia, is one of the most visited cities in the world, with more than 20 million tourists annually.

Washington, D.C., is a national center for the arts. The John F. Kennedy Center for the Performing Arts is home to the National Symphony Orchestra, the Washington National Opera, and the Washington Ballet. The Kennedy Center Honors are awarded each year to those in the performing arts who have contributed greatly to the cultural life of the United States. The historic Ford's Theatre, site of the assassination of President Abraham Lincoln, continues to operate as a functioning performance space as well as a museum.

The Marine Barracks near Capitol Hill houses the United States Marine Band; founded in 1798, it is the country's oldest professional musical organization. American march composer and Washington-native John Philip Sousa led the Marine Band from 1880 until 1892. Founded in 1925, the United States Navy Band has its headquarters at the Washington Navy Yard and performs at official events and public concerts around the city. Washington has a strong local theater tradition. Founded in 1950, Arena Stage achieved national attention and spurred growth in the city's independent theater movement that now includes organizations such as the Shakespeare Theatre Company, Woolly Mammoth Theatre Company, and the Studio Theatre. Arena Stage opened its newly renovated home in the city's emerging Southwest waterfront area in 2010. The GALA Hispanic Theatre, now housed in the historic Tivoli Theatre in Columbia Heights, was founded in 1976 and is a National Center for the Latino Performing Arts.

The U Street Corridor in Northwest D.C., known as "Washington's Black Broadway", is home to institutions like the Howard Theatre, Bohemian Caverns, and the Lincoln Theatre, which hosted music legends such as Washington-native Duke Ellington, John Coltrane, and Miles Davis. Washington has its own native music genre called go-go; a post-funk, percussion-driven flavor of rhythm and blues that was popularized in the late 1970s by D.C. band leader Chuck Brown.

The District is an important center for indie culture and music in the United States. The label Dischord Records, formed by Ian MacKaye, was one of the most crucial independent labels in the genesis of 1980s punk and eventually indie rock in the 1990s. Modern alternative and indie music venues like The Black Cat and the 9:30 Club bring popular acts to the U Street area.
