Jaws

In the first scene of Jaws, the music starts diegetic, then when the boy and girl leave the group the music is diminuendo because they are getting further away from the fire. When the scene was in the sharks point of view, the music started playing a crescendo when it was approaching the girl in the water. When the girl was being dragged around, the music speeds up and so does the speed of her being pulled around the water.
