A field of possibilities : designing and playing digital musical instruments / Per Anders Nilsson.

Diss. Göteborg : Göteborgs universitet, 2011

This thesis focuses on a set of digital musical instruments I have designed and developed with ensemble improvisation in mind. The intention is not to create a universal improvisational instrument, but rather to create a set of instruments which each realize one musical idea. My research addresses the meaning and relations between activities in two stages, what I call “design time” and “play time”. In short, design time is conception, representation, and articulation of ideas and knowledge outsi... mer de of chronological time, whereas play time takes place in real-time and concerns bodily activity, interaction, and embodied knowledge. In this work aesthetics play a crucial role, and here signify what is important for me. At design time my aesthetic preferences guide the design process, whereas in play time, a subjective aesthetic tenet is that musical improvisation has strong similarities to gaming and play. One hypothesis states that choices made during the design process at the development stages of a digital musical instrument significantly influence ensemble improvisation and musical results at play time. A digital instrument in this work constitutes a field of possibilities, which in play actualizes the aesthetic decisions of its designer, and in cases where the designer and player are one, during play there will be a double influence: directly through the player's actions, and indirectly through the nature of the instrument.
