Jaws Opening Scene

In the opening of the clip, the colour an brightness of the location is that of a dark and sinister vibe. The location is a juxtaposition to the feeling and situation that the people on the beach are having, as they are enjoying themselves. However the location and its environment suggest otherwise as it has a more sinister and gloomy look to it.
From 1:25 to 1:35, a POV is used from the from the sharks perspective to build up curiosity and tension within the scene, as looking form the sharks point of view, with the viewer not aware that they are looking from the sharks POV, so the scene is building up to a climactic encounter as the music which also coincides with the shot, builds up the dramatic effect in the scene as the music has low pitched sounds which gradually grow in pitch and pace as the clip goes on to increase the tension in the shot.
Furthermore, the shot at 2:35 shows the baron view of the sea, and that the viewer nor the man laying on the beach, no longer know where the girl has been taken into the see, creating a errie and uneasy atmosphere as both the man in the clip nor the audience are aware of where she is.
At 1:50 in the clip, high pitched noises are made by a string instrument like a violin. This is done to create panic withing the scene as the girl is being pulled by an unknown creature (Shark). A tense and uncomfortable feeling is created as the high pitched sounds are unpleasant on the viewers ears, making the whole scene an uncomfortable viewing as no one knows what is really happening in the scene apart from the girl fighting for her life
