Film Form Revision - Sound

 90-100% of sound and dialogue is added in post-production, even 'silent films added music

Diegetic sound- Coming from the story world and the characters can hear it

Non-diegetic- Not coming from the story world where only the audience can hear this. Non-diegetic sound can manipulate the emotions of audiences and creates meanings.

Internal diegetic- A characters thoughts. It's coming from the story world but only the character and the audience can hear it.

Synchronous sound- You can see the object making that sound. 

Asynchronous sound- Sound that is offscreen. You can't see what is making the sound.

Contrapuntal- The sound contradicts the images and they don't match. (this links to Sergei Einsenstein's Intellectual Montage)

In this image, Sergei Eisenstein shows how his face next to different images creates different emotions. An intellectual montage is the editing together of clips to create an intellectual or ideological montage. Einsensteins intellectual montage was an idea that derives from the collision of two shots that are independent of one other. This links to contrapuntal sound as the sound contradicts the image such as a sad sound playing during a happy scene.

Sound Layers- Sound is built in many layers, sometimes even hundreds of layers

Sync and Wild sounds:

Dialogue and sound effects can be broken into a category which relates to the picture reference that is used during there creation. The terms used are sync and Wild

Sync sound is a sound that is recorded with reference to pictures, e.g. dialogue, location sound effects. This is often replaced later. Dialogue is often replaced with A.D.R and sounds are replaced by sound effects.

Wild sound is sound that is recorded with no reference to pictures e.g. atmospherics.

In the Scotty nightmare sequence, Hitchcock used percussion instruments to create a eerie feeling. The music reflects on the scene as it creates the mood for it. The music is non-diegetic as it is added in post production and is not a sound that the characters can hear.
