Music and other sounds also define Bergman's style. This includes the prologue, with a "discordant" score accompanied by dripping and a ringing telephone. In the scene where Elisabet meets Alma in her bedroom, foghorns accompany Werle's music. Musicologist Alexis Luko described the score as conveying "semantic meaning" with "diabolus in musica" ("the devil in music"), a common style in horror cinema. The addition of a foghorn indicates a meeting of "diegetic and non-diegetic", complementing the breaking of the fourth wall when Alma and Elisabet look at the audience. The music Elisabet hears in the hospital, Bach's Violin Concerto in E major, is meant to be "nice and soothing" and divert Elisabet from her mental torment. It fails to comfort; Wood calls it one of Bach's "most somber and tragic utterances", and the scene's lighting darkens accordingly. According to Luko, Elisabet's lack of sound (muteness) makes her fit "the cinematic profile of a powerful, pseudo-omniscient mute".
