music tracks in films

music has a very key roll in film. it sets the scene and the mood of the scene. without it film would be boring.
afew examples:
jaws. jaws uses music to build suspence in a scene for when the shark is about to attack "jaws theme" (by john willams) with out this legnedary track playing in the back round the scene would have no fear fact at all. in this film its the song that makes it good
inseption. this has 2 amazing tracks to make it such an epic film one is "Dream Is Collapsing" this sound track starts sinister but then progresses (as the scene dose in the film) into something very dark and chaotic as everything starts going wrong around them inception scene . the second track is"time" this one has much happyer conertations. its used at the end of the film when the main charater completes his mission and gets to see his kids again but the end is soft and sad to remeber the loss of his wife and to leave the film on a major cliff hanger. its very moving track that show the audince the emotions that the main charater is feeling. end scene (both songs by hanz zimmer)
these 3 songs are original scores made for the film but you can also use borrowed music that is already around before the film is made. eg plup fitction ( cant find a link sorry. more on that soon :)
