Editing Process: Adding Sound to Anchor the Plot

A conventional feature of a trailer is to have some sort of sound included, whether that is dialogue, ambient sound, diegetic sound, non-diegetic sound or foley - all of this accounts for anchoring the genre and tone of the trailer. When picking music I had to make sure it was appropriate to match the tone of the shots, e.g. if the scene is eerie and spooky, having a running soundtrack over the top of happy and joyful music would completely disrupt the tone of the trailer and thus may confuse the genre.

At the beginning of the trailer the equilibrium is in balance. To connote this I wanted to have a fairly simple running track under the shots for this section of the trailer. I chose a fairly upbeat and positive instrumental song - "Wiffle Ball" by Joel P. West.
This enhanced the harmonious balance of the equilibrium and the audience were able to understand this with the combination of non diegetic sound and camera shots. 

As the trailer moved forward through out the plot, there was a break in the equilibrium as the killer is introduced. I used changed the track to a darker , more mysterious and ominous vibe. This helped anchor the idea that this male character on screen (killer) is associated with a dark and unwelcoming presence. When this music is heard there is a change of tone and the killer appears, ultimately the audience subconsciously take note of the change of tone and therefore they understand that the equilibrium is about to be disrupted. For this section of an ominous atmosphere I used the track "Radius" by Hi-Finesse. This track added a jarring and scary ominous sound to the trailer 

In addition to adding two tracks to contribute to the anchoring of the plot, I also added loud, scary and ominous sound effects and ambient sounds to enhance the thriller genre.
