Throughout the film, A Clockwork Orange, the orchestral soundtrack as well as the sound effects – which are often tied together throughout the film – are utilized to not only convey the psychological state of the main character, Alex, but to create a mirror with the emotional experience that the audience undergoes (which lies in parallel with Alex’s own psychological journey). As Alex experiences a certain psychological hysteria – a high of sorts – in the actions of completing his delinquent crimes, the music that we hear reflects his chaotic state of mind, projecting it onto the audience. As the classical music clashes with the actions and setting, not only portraying but giving insight into his deranged mind – we absorb it all. The blatant discord between the situation at hand and the music overlain creates a sense of hysteria and harmonious confusion within the audience, maybe even nauseousness.
In that sense, we are able to connect with Alex’s character, seeing through his eyes and mind vicariously, using the sounds and their interaction with the visual cinema as vessels. For example, in the scene where Alex daydreams, a very ominous brass instrument-heavy melody begins, then followed by a serene violin solo, expressing the peaceful, dream-like state within Alex’s mind.
Also, it seems that the use of classical music almost completely embodies the emotions Alex is feeling at the time it plays; his love and enthusiasm for rape and crime is manifested in his love for Beethoven, as music is blasted loudly and shamelessly during Alex’s moments of euphoria and the most seemingly disturbing and morally-unhinged of scenes.
The absence of music throughout the film often signifies Alex’s disconnect from the rest of the world – his isolation from it – as well represents how the world has turned into a force bent on destroying him, his victims now having become his oppressors.
