Sound Deconstruction - The Woman in Black

I deconstructed the sound in a clip from the film The Woman in Black made in 2012. This is the YouTube clip and the link:

 

This scene in the ‘The Woman in Black’ begins very quietly, immediately leaving the audience awaiting for something to happen, when suddenly a gentle bumping noise can be heard, getting slightly louder. As the character gets up to follow the diegetic sound, the knocking gets increasingly louder and almost forms a steady beat. Tension is then built up as not only is the noise getting faster, but as the character gets closer to the door the thumping sound gets faster too.

0:15 - By the time the character reaches the door the sound is so loud and vigorous, making the audience feel tense and on edge. He then reaches for the handle and the diegetic harsh rattling sound is used to show us that the door is locked so he is unable to discover the mysterious sound which is now very intense.

0:32 - However, he runs back down the corridor and down the stairs to fetch a large panel to knock down the door, and as he moves we hear his footsteps thumping on the wooden floor and a non-diegetic sound is introduced. The creepy soundtrack is composed by string instruments which are very effective in again creating a tense atmosphere.

0:35 - A few seconds in, another string instrument in a slightly lower key is heard, and the music then gets increasingly louder until all the string instruments are getting higher pitched. This is a common sound in many horrors, and works well because it builds a lot of suspense in the scene, leaving the audience feeling very apprehensive.

0:41 - Suddenly, the non-diegetic soundtrack fades out and the only sound that can be heard is the intense thumping again. This is really effective for this moment in the scene because as it happens, we see that the door has mysteriously unlocked and is wide open at the end of the corridor. This creates so much suspension and effectively leaves the audience very on edge.
