sound used in thrillers

Sound:

Sound is used in thrillers to help the audiences understanding of what is going on. Sounds are used to evoke characters feelings and emotions and get a response from the audience. It is also often used to symbolise both the protagonists and antagonists movements in the scene. By carefully using the sounds employed in the scene it creates the right mood and atmosphere and in the context of the thriller genre, helps to build suspense and tension.Thrillers are typically noisy and they uses lots of diegetic sound throughout the film. Common sounds include bangs, ticking and screams, they use these sounds to build tension and to create suspense. These sounds are normally heard by both the audience and the characters and they are normally very jumpy. Non diegetic sound is also used in thrillers. They sometimes use a steady drone which puts the audience at unease. Also as the action increases in the film and the tension builds the music speed up and increases in unison. Hitchcock used sound in a very new way than was typical at the time. For instance in Blackmail he demonstrates ongoing tactics, such as: withholding sound from the viewer to pique curiosity which is shown in the murder scene http://www.youtube.com/watch?v=POMvKwfBVWo, there is no sound during the murder and we can’t see what is happening which leaves us wondering what exactly is going on. It subverts our expectations of a murder as we would expect lots of screams but we don’t get anything. He also exaggerates sound as a form of narrative emphasis and creating tension through both ambient noises and silence. Further, in a world where music was the dominant form of narrative accompaniment, he stripped music score away from his scenes and instead used the act of singing (and whistling) as a suspense device. Lastly, Hitchcock’s manipulation of human speech ranged from technical malfunctions of telephone calls to dizzied audio abstraction of the characters’ subjective thoughts.
