Sound analysis

As an example for my sound analysis, I will use 'The Girl with the Dragon Tattoo'. It starts out with a faint introduction to the music, with non-diegetic screams included however this only occurs at the start and end of the sequence. These screams infer a theme of pain, peril or danger that will recur throughout the film, which in turn being a typical thriller will have the audience on the edge of their seat. This also instantly shows that this film is going to be an action and psychological thriller, as it follows a stereotype of women being put in danger, which is commonly used in psychological thrillers.
The song 'Immigrant Song' is played which is a fast paced, loud song. This cuts a clear impression to the viewer that this film is going to be fast paced throughout, and there will be no slowing of the pace in the film. In other words it will escalate quickly and hold that pace. This means it is synchronous sound since it matches the genre and action of the film since it is evident this film will be fast paced with the choice of the song. The fact it is a female vocalist singing the song, however, connotes this film will be about the empowerment of women, fighting back since that is what the song is about.

Towards the end of the sequence, male and female screams are heard which in turn shows there is now danger to both the sexes. It becomes obvious that a male character will be used since the danger towards men has also been expressed and put across by faint non-diegetic sound. This could mean a change in social stance between the male and female characters who could potentially be involved in the plot.
Also, the music suddenly cuts out meaning the film's action will end very abruptly, after a resolution occurs. With it being synchronous to the plot, it gives a strong inference that the ending will be quick and abrupt after a heavy action scene. Possibly resolved by combat and the abrupt music stop represents the stop of a heart or bodily functions. These are all typical conventions of any action-thriller and effectively keep the viewer on the edge of their seat, since opening soundtrack is repeated throughout the film to clarify that actions scenes are either currently occurring or are about to occur. The use of high paced synchronous music effectively engages the viewer because subconsciously they will know the film will be packed with action due to listening to the music.
