The Imperial March was composed by John Williams for Star Wars: The Empire Strikes Back in 1980 as Darth Vader's theme, and it has since become shorthand for villainy in film, television and internet culture. Hot Symphony is a short, intensified remix of that theme that circulates on soundboards and in short-form edits, where its compact length makes it easy to drop into memes. Its staying power comes from instant recognition: even a few notes signal power, menace or comic self-importance.
