Sound is important in horror films to enhance the audience's emotional experience and create tension. Music can underline characters' unspoken thoughts, build continuity between scenes, and signal when tension rises or falls. Effective horror film soundtracks represent characters, set locations and time periods, parallel the action, and create convincing atmospheres. Iconic horror film scores, like those in A Quiet Place, The Return of the Living Dead, It Follows, Halloween, and The Descent use music, effects, and silences to generate anxiety and fear in viewers.
