Darth Vader's Theme vs. Beethoven

Well, that would be in keeping with the way Williams himself used the Leitmotif in Darth Vader’s death scene, where Darth asks Luke to remove his mask. Most of the themes that John Williams came up with for Star Wars were repurposed even in the first movie, with the Jedi theme originally as a haunting reminder of faded magic repurposed into a Wagnerian triumph march at the end.

Williams himself has been very open about how he took the idea of a Leitmotif from the romantic composers (Wagner, Tchaikovsky, Holst, and so on) and repurposed it for the modern cinema.
