Sounds

Sound is a big part of making different atmospheres and moods through out films.  They can create tension and suspense but also create happy and peaceful moods.

There are different types of sound.  One kind would be if the sound is diegetic or non-diegetic.  If it is diegetic then the sound refers to the world of text, which means it could be dialogue, or sound effects.  However, if it is not diegetic then it refers to everything outside of the world of text, which means it could be a voice-over or a soundtrack.

The sound could also e on screen or off screen.  On screen sound is when the audience can see the source of sound, however, off screen sound is when the audience are not able to see the source of the sound which means it enables the extension of the diegetic world.

Also, sound can either be parallel or contrapuntal.  If the sound is parallel then it will match with the actions shown in the film.  However if it is contrapuntal then the sound does not match to the action in the film.  For example, in Jaws when the woman is swimming in the ocean she seems happy and peaceful even though the sound is very intense.

Finally sound can contain bridges which are called sound bridges.  They help to create a smooth transition between one scene to another.
