Classical music is used excessively in this film, as both diegetic and extra diegetic music. In the beginning of the movie, the volume of the music was louder when Alex and his gang were committing the violent crimes. The loud music heightens the suspense of the scene and evokes a greater emotional response with the audience. The classical music, especially Beethoven’s 9th Symphony, was diegetic when it was being played in the house and Alex was locked up in the room upstairs. It was extra diegetic when it was being played on the loud speakers in the hospital. At that point, all we could hear was that music and nothing else as the camera made a close-up to Alex’s agonized face. The 9th symphony was a way of controlling Alex. At first it was one of his favorite songs, and he listened to it to calm himself and relax. But after the treatment it becomes a cruel torture device.
Another aspect of sound that stood out to me in the movie was how the dialogue and music intertwined tremendously. Because Alex is the narrator of the whole movie, the music had to coincide with what he was saying and the actions that were happening on screen. I noticed that even when he was talking, the classical music in the background would still be playing as loud as it was before he was speaking. The classical music complements what Alex is saying, especially during the crimes he was narrating.
The music plays with our emotions and thoughts in a way that contradicts what is actually happening. For example, in the scenes where Alex is forced to watch the disturbing videos as part of the experimental treatment, there is upbeat, joyous classical music playing in the background. This distorts our expectations of what music we would expect to be played in a scene like this.
