Movie trailers have one goal: to capture your attention inside of a minute and make you want to see the film. They do this through clever tag lines, through showing some key scenes, and of course, through some emotive or pulse-pounding music. Several movies use music from the scores to introduce their premises and give you a preview of what to expect in the film. However, there are also those who compose 2 to 3 minute songs for the sole purpose of being used in a trailer. Some are extremely successful at it. Some of these songs have been used dozens and dozens of times over for numerous movies, each time exciting viewers as if it were brand new. These pieces can also work while writing a tense scene in a novel or when you are trying to write your back cover blurb or describe your book on your website.
