What are some good music editing and composing programs?

I don't really know what it's called, but I need a program that I can actually make music on. You know, type in the notes and it puts it all together for me. I don't need anything like Finale where you can only write the music then print it, or Garage Band that you have to record your sounds first. Does anyone know of any good programs in which I can make my own music? At the moment I am trying to put together a movie score on my own for a contest so to speak. Thanks.
