A sound analysis of the first 3 minutes of The Exorcism of Emily Rose.

Throughout titles:

• A strong, low monotone at a slow pace.
• A high tone is introduced creating a blend of eerie tones and raising uncertainty amongst the audience.
• The non-diagetic sound is parallel to the narrative - unsettling and hinting the horror genre.

Black Screen:

• The non-diagetic sound continues.
• Diagetic sound is also introduced overlapping the soundtrack - Although not entirely clear what these sounds were, it sounded like wind, animals, screams or someone in pain. 
• Is use of dialogue when a female character screams 'Emily?!' - hints danger, pain, distress and lack of power. It specifically intrigues the audience. It seems from the diagetic sound that there is a female protagonist - a stereotypical role of a female in horror film (what is expected ).

Fades to white screen, then imagery is introduced:

• As the title of the film is shown, the screaming stops. Meanwhile the low monotones of the non-diagetic soundtrack are still present.
• Diagetic sounds of howling wind, the rustling of crops and footsteps highlight the silence surrounding the old, male character. It portrays isolation and emphasizes how alone the character is - not safe.
• As the film proceeds, the high non-diagetic tones remain, however when a character feels uneasy, the low tones are re-introduced.
• The sounds of object which are affected by the wind create squeaking, unsettling noises.
• In addition the sound of small animals and wasps hiding for safety indicates a sign of danger. This has raised the tension, and the audience now expects a climax to take place.
• Conversation only starts when the film reaches 3:00 minutes approx, demonstrating that the film has successfully built tension using imagery and sound, showing the audience of the specific codes and conventions of the horror genre.
