ALWAYS LINK BACK TO THE GENRE 

Enigma - Person or thing that is mysterious, puzzling or difficult to understand.

Jaws

Locations: Beach either late at night or early morning.

Music starts about a minute in, faintly in the background. Gets louder and faster. Contrast between louder music during the attack and after with the man lying on the beach. The foley in this scene was the splashing water and the screams of pain.

Before the attack, there is a panoramic image of the sea with the girl swimming in it, then after towards the end, there is the same image but missing the girl. 

Genre was clear throughout the scene that is was a horror/thriller due to the screams and the mystery as to what is happening (enigma)
