Analysing Language in Documentaries

I think a lot of things can change what we see in documentaries, like the scenes, way it is shot, sounds etc.

Here are some things I think that sets the mood of a documentary:

Techniques			Effects
Low toned, slow music			Scary, a lot of tension
Fast, high pitched, major key			Happy, exciting, pleasant
Slow with a subtle mix of both keys, no sharp instruments			Relaxed, calm, peaceful
Speeches from people with negative thoughts			Inspires the viewer to think negatively
Speeches from people with positive thoughts			Inspires the viewer to think positively
Fast panned scenes			Lots of things going on, lots of tension, very action-typed-movie-like.
Slow panned scenes			Relaxed, not a lot going on
