Sound

The opening scene of Jaws begins with a group of teenagers sitting around a campfire. For now, only diegetic sounds are heard, for example: talking, guitar playing and laughing. Two teenagers begin to isolate themselves  therefore the diegetic sounds coming from the group begin to die down and the only thing you can hear is the girl and the boy talking. The young girl then begins to go in the water. The camera is then put at an angle which imitates the shark's point of view. Low, non-diegetic string music  begins to play in a crescendo which suggests something is about to happen. The shark then manages to attack the girl and high pitched strings are playing in a sforzando way which symbolises her fear and the sound of the water splashing. The diegetic sounds are her screams and the water. When she dies and her head goes underwater, the music comes to an abrupt stop which represents the end of her life.

 



In the Godfather, a majority of the sound is diegetic. A diegetic crescendo sound of a train plays which builds up and gets louder. The train abruptly stops as soon as he shoots the other man.

Diegetic: sounds that are within the scene. (e.g. talking)
Non-diegetic: music that is added afterwards in post production.
Crescendo: the build up of sound and music.
Diminuendo: gradual ''die away'' of music.
Sforzando: sudden sharp sound.
Diegisis: the context it is in.
