In my film I'm either going to use a clock ticking or a music box as background music. One of the reasons I'm looking at using one of these two different sounds is that the clock is a classic sound for the genres im looking at doing, also it gives you the impression that their time is running out. The music box on the other hand is an innocent sound but if its used in a horror film makes it seem even creepier as most people associate music boxes with innocence and children.
