Submarine is an acousmatic work that was motivated by the catastrophic suffering that the Kursk submarine crew must have endured during their entrapment at the bottom of the ocean whilst facing their inevitable death. This event set forth the realisation that I had become increasingly desensitised to the world, therefore, submarine can be viewed as an introspective analysis of my own emotional reaction to the disaster. The overarching aesthetic is to aurally concretise emotional states; potential subjective states that can be produced when one emotionally relates to a catastrophic event. This is partly achieved by the sonic material used and through public domain knowledge of the disaster presented by the media. The piece makes use of the 'horrific' and attempts to reproduce anxiety through the externalisation of emotionally generated material such as intense screaming, sounds of asphyxiation and the gestural articulation of words and other sonic events (the words twenty-three in section 3). Submarine makes use of 'affiliated' materials organised and manipulated in order to produce sonic landscapes and features that could be related to the Kursk submarine disaster. Inherent gestures located in the sonic material are caricatured, magnified and augmented in order to produce emotional states within the listener through sonic documentary and metaphor.
