Analysis of past students work

This is my analysis of past students 'Thriller Opening' work, it is a film called 'The Night Walker'. This opening begins by showing someone playing music on a piano, to the same melody and rhythm as the music playing throughout the clip. The person playing the piano had bandaged, bloodstained hands which conveys a sinister atmosphere. 
  The music is used to build up suspense, which will entice the audience. They use shots of the person cutting up pictures, which further conveys the sinister nature of the film and further builds suspense.The identity of the person is never revealed which keeps the audience thinking and interested. They mostly use music in this clip to portray the atmosphere as there is minimal dialogue. Diegetic sound is used. 
  In addition, the camera movement is impressive as it is clear that they did not use a tripod and simply carried the handheld camera, making it harder to keep steady but they did a good job and the slight shaking gives the film a rough edge which goes well with the theme.
