The opening sequence of Jaws uses sound, cinematography, and mise-en-scene to create suspense and tension. It begins with the ominous shark theme music that puts audiences on edge. Shots from the shark's point of view under water are intercut with shots of oblivious teenagers that show we have information they don't. When Chrissie swims alone at night, ominous music plays and shots from above and below frame her as vulnerable prey. Her isolation and the peaceful setting mislead her and viewers about the nearby threat, increasing the horror of her attack.
