The music in a film plays a very big part. The music emphasis an action. This also suggests the genre and sets the mood for the film before it is fully watched. Automatically when we hear a scary sound in a film we automatically think that something scary is bound to take place.
I used three different soundtracks for my short film which are very modern, in terms of sound technology but suit the overall vibe of danger and threat, with the support of heavy drums and low bass synths.
