The music is presented  with the presenting of the cast which are displayed in big sharp white fonts across big high buildings which give the audience a feel of what the film may be about. The music is very eerie and starts of low and then high leaving the audience feeling intense and left with an idea of what the film may be about and what they may be expected to see.
