Jaws

Jaws is a very good example of a movie where music plays a critical part on the effect of the movie on the audience. The music helps create the tension, when you see somebody playing in the water and the ¨shark is coming" music starts playing you know what is about to happen, you are expecting it and you are afraid. The music is meant to give you that feeling that something terrible is about to happen and it makes you wanna scream at the movie, tell the characters to get out of the water, but unlike you they don´t hear the music. Wouldn't it be nice if music played in real life when something was about to happen to warn you?
