Jaws uses a great deal of juncture position during it's opening scene. The music is not at all what would be expected for most horror movies, flowing light and airily rather than trying to create suspense. However, Jaws does not attempt the obvious effect of suddenly reverting to a sharp, loud music to create a horrific effect, instead the director is much more subtle.

The juncture position is instead created by the continuing of the light, positive music while the women in the water the opening scene focuses on moves more and more frequently. At first it seems that she might just be splashing about in the water, and with no change in tone from the music the audience doesn't give it much thought. That is, until she's flailing more and more violently, in which the audience starts to suspect something is amiss.

The true horror of the scene may not be fully realised consciously by the audience, the continuation of the happy music may just be thought to miss lead them, but as it continues while an innocent and vulnerable women is in danger, it gives an impression that someone is enjoying her suffering, almost like someone who murders with a smile on their face.
