The effect of a good soundtrack

Everybody that watches a film will notice music in the background for most films so it sets the mood, for instance in a martial arts film there's usually what you'd call 'up-beat' motivational music so it gets the blood pumping and the mind focused, in a horror there's usually a use of eerie music that slowly builds up in tempo, action films have usually fast paced 'heavy' music, so the music choice by the production team has to be critical to the movie and reflect it's narrative so it's delivered in the right way so the viewer gets the right message. My opening has the soft acoustic that's quite eerie so it shows that the opening is a very serious film and is not for instance a comedy.
