Movie Trailer Music

Most action movie trailers are made the same way music wise. The clip starts out with slow and quiet, or no music, as the video introduces the setting and characters of the film. As the clip progresses and some action starts showing the music starts to pick up in speed and volume. As the film is introduced there are flares of music to mirror the bursts of images and information portrayed by the video.  In decisive moments before something dramatic happens the music dies down building up the suspense the silence breaks and something dramatic happens. The music keeps building up all the way to the end of the clip, and breaks as it reaches climax. Abruptly transferring back into slow, quiet, often mysterious music that leaves you hanging and wanting to watch the movie.
