John Williams’ “The Imperial March” from The Empire Strikes Back is a G minor, brass-driven theme that uses a rising perfect fifth and descending minor third to convey power and authority. Its steady 4/4 march rhythm, reinforced by snare percussion and dark string harmonies, mirrors the Empire’s military discipline. Built in a ternary form, the piece contrasts its aggressive main theme with a smoother yet still ominous middle section before returning with greater force. Drawing on Romantic influences like Wagner and Holst, Williams uses the leitmotif to give Darth Vader a musical identity that embodies intimidation, inevitability, and unrelenting strength.
