The Throne Room, Victory March, or Force theme, is a song written by John Williams and performed by the London Symphony Orchestra.
In the movies Edit
The Walton-esque piece is played during the medal ceremony at the end of Episode IV. Williams develops it into a set of chromatic variations during the scene in Return of the Jedi in which the Rebel fleet takes off into hyperspace. A longer rendition was written and recorded later (heard on the Skywalker Symphony album). This extended version was also recorded for the album version of the end credits for Episode III.
