This PhD is centered around a discussion on some of the different notions of environment in electroacoustic music, supported by a portfolio of original compositions. A central, overarching notion, present throughout this portfolio, is that of physical and cultural environment. These distinct types of environment are explored at length, through the lens of this varied musical portfolio, covering fixed medium, stereo, multi-channel, live-derived and game-related. This diversity in formats informs my evolving understanding of environment in electroacoustic music, and suggests different performance setups, which are explored as a conclusion of this research.
