Embodied Expressions is an exploration into the possibilities of creating live audiovisual performance systems with the aim of expanding my own artistic practice. This thesis investigates how a performer could express more intuitively with physical and mechanical audiovisual interfaces, and stands in revolt against the total digitalization of live electronic music. I argue that modern electronic music performance has led to a decoupling of sound from its traditional origins in real physical objects and has created a limitation in the live performer’s ability to express themselves through the embodied aspects of their live musical expression. This thesis reflects on the artistic exploration of embodied instruments made up of found objects and their control by a performer’s gestural input. The final artifact of this thesis is a set of heard and seen mechanical instruments placed about the audience’s environment that are controlled by the performer using a custom-designed gesture-based control system.
