Research and Planning - Sound Test

I have been playing around with sounds and instruments on Garage Band to create a rough score that could be associated with the genre of horror. This is my first time using Garage Band for its proper purpose. As I can play keyboard/piano, I already knew a few songs/tunes which I could re-create in Garage Band and mess around with them to make them sound more 'horror' style - such as the title overture of Phantom of The Opera and Mad World by Gary Jules. Aside from creating a score in Garage Band in media class, I have been messing with a few different electric, bass and acoustic guitar riffs at home, which would fit nicely with a horror style film trailer.
