Music is a performance art. Among musicians, music is something you do and feel: it has a strong kinesthetic component, existing not only as sound, vivid aural imagery, and music notation, but also as patterns of movement. In this lecture, Hanninen sets out to develop a theory for the kinesthetic analysis of musical movement that attends not only to the complex choreography of precise physical actions suggested by Western music notation, but to intentional aspects and felt qualities of motion from a first-person perspective. Throughout the lecture, she considers some of the fundamental challenges of doing this work, which include problems of ontology, language, and research methods.
