The Orphic I: A Philosophical Approach to Musical Collaboration starts from the premise that music is a realm of intersubjective human experience. Drawing on ideas common to both hermeneutic and pragmatic aesthetics, it examines forms of collaboration involving those who create, perform, and listen to music. A new interpretation of the Orpheus myth suggests a model for thinking about creative interactions where composer and performer adopt each other's perspectives. This imaginative transfer of self--the Orphic I--has significant implications, both for the listener's perception of authenticity in musical performance, and for the interactions of performers within a musical ensemble. Empathy and entrainment emerge as seminal animating forces in group music-making, providing a non-verbal basis for ethical decision-making among group members.
