Sound

Sound

Diegetic:

Diegetic refers to the world of the text, it is sounds that the characters would be able to hear. For example dialogue, sound effects, music with a source within the world of the film e.g. a radio.

Non-Diegetic:

Non-Diegetic refers to everything outside the world of the film, it is sounds which the characters would not be able to hear. For example voice over, soundtrack.

On-screen sound- the audience can see the source of the sound.

Off-screen sound- the audience cant see the source of the sound. 

Off screen sound enables the extension of the diegetic world.

Parallel sound matches the action on the screen for example in a chase there is a fast pace soundtrack.

Contrapuntal sound does not match the action for example in a chase there is a slow pace soundtrack.

Sound bridge creates a smooth transition between one scene to another, the sound 'bridges' across the two scenes.
