Sound

On screen sound: the sound we can hear is coming from something on screen e.g. we see someone talking on the telephone.
Off screen sound: we can't see where the sound is coming from e.g. outside the room.
Diegetic: sound we hear as actors
Non-diegetic: something put in afterwards e.g. soundtrack and voiceovers.
Dialogue: how its spoken, not just what is said.
Foley sound effetcs: sound effects put in for silent movies e.g. rice in a jar for rain.
Voiceover: getting inside characters' heads, thoughts/feeling, or a narrator explains what is going on.
Parallel: music and sound matches the action e.g. slow motion running across a field to meet a loved one = soft romantic music.
Contrapuntal: music and sound doesn't match the action e.g in Clockwork Orange when people are being tortured in their homes,Singing in the Rain (a cheery song) is playing.
