Battle of the Heroes

"Battle of the Heroes" is a musical theme from the movie Star Wars: Episode III – Revenge of the Sith. It was written by John Williams for the duel between Anakin Skywalker and Obi-Wan Kenobi on the volcanic planet Mustafar. Williams wrote the piece upon the request of George Lucas. Lucas wanted a piece that would function as a "tragedy Duel of the Fates" in the film's final fight scenes.

The concert suite begins with a soft and tense ostinato by the violas in tremolo. Stopped horns join in to present an initial statement of the theme, immediately followed by pulsing beats with mezzopiano double basses and cellos. The ostinato builds as the harp and trombones make their entrance. Suddenly, the horns, 1st violins, and choir play the theme at a louder dynamic level. The ostinato still plays beneath it all. Twice, the theme is interrupted by brief flurries of chaotic "action music". At a key moment, the "Force Theme" makes a forceful entrance in a minor key. After the piece's main theme is heard several more times, "Battle of the Heroes" culminates in a fortissimo tutti of repeated D minor chords. This false ending is followed by the viola ostinato again. Solo flute, oboe, English horn, clarinet, and horn in unison deliver a melancholic interpretation of the theme's third over the ostinato, which slowly dies away before landing on the tonic. The timpani rumble as the entire orchestra crescendos into a final D minor chord.
