Sound

On screen sound: This is when the audience can see the source of the sound, for example, the people on the screen, or items being used.
Off screen sound: This is when the source of the sound is not on camera, so the audience can't see it, but is still diagetic, such as a a fight off screen.
Parallel: This is when the sound matches the action, for example, Some slow, tense music would do well in a horror film, as the tense music matches the suspense.
Carpunctual: This is when the sound does not match the action, such as tense, horror music in an action fight scene.
Diagetic sound: This is what can be heard by the characters of the film, such as gunshots, footsteps and talking
Non-diagetic: This can only be heard by the audience, such as heartbeats or background music.
Sound bridge: The sound bridge helps shots transition smoothly between each other, for example, a dream being ended by an alarm clock, starting the day.
