The film was Herrmann's first motion picture score and would be nominated for an Academy Award for Best Original Score, but would lose out to his own score for the film All That Money Can Buy.

Herrmann's score for Citizen Kane was a watershed in film soundtrack composition and proved as influential as any of the film's other innovations, establishing him as an important voice in film soundtrack composition. The score eschewed the typical Hollywood practice of scoring a film with virtually non-stop music. Instead Herrmann used what he later described as '"radio scoring", musical cues which typically lasted between five and fifteen seconds to bridge the action or suggest a different emotional response.
