This portfolio consists of electroacoustic compositions which were primarily realised through the use of corporeally informed compositional practices. The manner in which a composer interacts with the compositional tools and musical materials at their disposal is a defining factor in the creation of musical works. Although the use of computers in the practice of electroacoustic composition has extended the range of sonic possibilities afforded to composers, it has also had a negative impact on the level of physical interaction that composers have with these musical materials. This thesis is an investigation into the use of mediation technologies with the aim of circumventing issues relating to the physical performance of electroacoustic music. This line of inquiry has led me to experiment with embedded computers, wearable technologies, and a range of various sensors. The specific tools that were used in the creation of the pieces within this portfolio are examined in detail within this thesis. I also provide commentaries and analysis of the eleven electroacoustic works which comprise this portfolio, describing the thought processes that led to their inception, the materials used in their creation, and the tools and techniques that I employed throughout the compositional process.
