Throughout TV programmes and Film there is always sound. Dependant on what is going on there are different types of sound;
Diegetic- natural sound within a scene, for example the characters speaking on the scene
Non- Diegetic- sound which is added to a scene such as a soundtrack. Potential problem is that is seems very unrealistic but a bonus is that it adds a lot more dramatic effect.
Sound Bridge- sound which carries on over two different scenes which then literally creates a bridge between two events. (two different locations)
Incidental Music- small, very brief snippets of sound to create emotion or feeling. (cultural code)
Asynchronous Sound- a natural sound, which is out of place and without a source on the scene.
Contrapunctual Sound- sounds which create opposite emotion to the one which is on screen.
