Soundrack for our thriller opening

Initially, our idea was to use the song 'Safe From Harm' by Massive Attack however we later discovered that this would not be possible due to copyright laws. Instead we had the option to search the internet for appropriate soundtracks free of copyright or to compose our own music. Coincidently, two of our three group members are studying A-Level music and thus opened the opportunity to compose something completely original for out thriller opening. This will be very beneficial as it can be created to fit the emotion within the opening and we can convey the exact message and atmosphere we desire. Our soundrack will consist of string instruments, drums and possibly electric guitars to create an atmospheric yet modern sound.
