Sound

The role and importance of sound/voiceover/music in trailers is to tell the story, express feelings and show the motivations of characters. They can create particular atmospheres and synchronous sounds give a sense of realism. Also, certain emotions can be created through music and its rhythm as it provides a tone and attitude of characters and the story itself. Changes in moods can also be foreshadowed for example inharmonious music can imply approaching catastrophe as it is not yet visible but the sound is subtle however the viewers are still aware. The sound relates with the visuals in a trailer which is a small amount of time to create an advertisement to reach out to the intended demographics. The voice over is like a narrator that gives specific details about the film and explains certain aspects. The sound also sets the scene and raises emotion at exaggerated points. In a conventional horror film trailer there are certain patterns such as orchestral music which is very common as it can vary through events and is very powerful. Long and eerie music is also commonly used to build up towards something through the use of strings which is then followed by orchestral hit.
