Psycho shower scene

During our most recent media lesson, as a class we watched the very famous shower scene from psycho. Whilst watching this we were also asked to make notes on things such as the creation of suspense, use of music, camera work and editing.
There were about 40 - 45 cut edits in the scene, the edits start off quite slow with the woman getting into the shower and then become faster and faster as the music begins when the curtain is pulled open.
The music used in this scene is very dramatic and high pitched with the use of violins to create a frightening and tense atmosphere. There is also a use of diegetic and non-diegetic sounds.
The most important uses of camera are when the woman is in the shower and the camera does a long shot of the woman so that you can see the killer coming closer towards the shower, another important use of camera is when the camera zooms into the plughole and then zooms out of the womans eye.
