Examples of the following:
- Intentional confusion of diegetic and non-diegetic sound
Mulholland Drive: The Silence theatre scene, the singer sings a song, we are sure her is singing and in the middle of the song she fell on the stage but the voice is still singing. Intention: everything is an illusion. As I am thinking about it it is diegetic sound because the characters in the film can hear it.
some examples from youtube:
- Sound that is hard to identify as either diegetic or non-diegetic
- Music (non-diegetic) used to identify social and cultural references
- Music and other non-diegetic sound used to create, for example, atmosphere, tension and emotion
Jaws: a signal that the sharks are nearby. (another example: http://www.youtube.com/watch?v=Ae1Z_fWDZ7s)
Psycho: the bathroom scene.
- Non-diegetic sound that sets the pace of s scene
- Non-diegetic sound that gives clues or cues to action
