Music within thrillers

I am focusing on a clip from the beginning of the film, the two protagonists have just reached the island and they are driving in a car towards the gates to the mental hospital that they are about to enter.

Within this film, the music moves from loud to quiet and vise a versa to create tension, there is also a lot of repitiion within the sounds. There are sharp sounds and occasionally siren sounds, there are deep orchestra and trumpet sounds. At the beginning of the film, as the boat approaches land and the protagonists take a car journey towards the centre of the facility, the music creates an ominous atmosphere. the music begins with a powerful low bass ostinatio.The climatic point begins when they enter a narrow brick corridor, and camera angle is from the view point of the car as they approach the gates; this makes the viewer feel as if they are inside the car with the characters; this builds a constant fear of the beyond.

Within this film, the music is generally builds from quiet to loud, there are also repetition of the music and of the sounds. There are moments of loud and dramatic symphonies. There are ambient sounds of waves and sounds of children in the background. There is an ambient calm tide coming in at some points of the film. An eery sound develops throughout the film. There are very sudden and sharp sounds for example screams.

Following on from these two analysis' - I have decided to compare their music to the opening sequence of 'Se7en'. The opening sequence of Se7en has more of a sci-fi sound and consisted of more computer generated sounds. This is different to the 'Shutter Island' clip as that clip contains sounds created by an orchestra rather than robotic sounds from a computer. This clip is also different to the analysis of 'Inception' as  throughout the clip I analysed it was loud all of the way through whereas the opening sequence 'Se7en' ends quietly. However it is similar to both 'Shutter Island' and 'Inception' as is has sharp thunder and lightening sounds during all of the clips.
