My dissertation project served as an opportunity to explore the various technical and aesthetical concepts of electroacoustic music composition. Over the last few years, my main focus was on composing a live electronic piece for an acoustic instrument and computer by creating my own method for composing, programing, and performing live electronic music. Hence, my dissertation project can be viewed as a twofold process: the first was composing Vocem Internum, or Vocem in short, for alto flute and electronics, and the second was a research project on the design of my own compositional method using MaxMSP by Cycling74. In chapters 1-6 of my support document I will discuss my compositional process and influences, provide a formal analysis of my piece, touch upon concepts of my decision-making process in regard to choosing materials and Digital Signal Processing (DSP), and lastly, explain the music notation process. Chapters 7-8 will focus on the reasons that led me to creating my own compositional method for live electronics instead of utilizing existing methods. Also, in these chapters I will explain the core and main design of my compositional system.
