Contained in this thesis are four works (The Last Day, Isolation Psychosis, Routines, and Intention) and their respective commentaries, and filmed performances of the guitar-based works (Isolation Psychosis and Intention) which comprise the body of my MMus composition portfolio, completed 2013. The music in this portfolio challenges the idea of traditional guitar performance techniques (Isolation Psychosis and Intention), and binary code as a system of composition (Routines). I take a different physical approach to the instrument of guitar in order to challenge my own technical capabilities, as well as those of other performers who may wish to perform my work. This approach was also taken to generate new technique-driven musical material with interesting and beautiful results.The commentaries exist to provide both technical and psychological insight into the creation of these works.
