We explore the phenomenology of embodiment based on research through design and reflection on the design of artefacts for augmenting embodied performance. We present three designs for highly trained musicians; the designs rely on the musicians' mastery acquired from years of practice. Through the knowledge of the living body their instruments – saxophone, cello, and flute – are extensions of themselves; thus, we can explore technology with rich nuances and precision in corporeal schemas. With the help of Merleau-Ponty's phenomenology of embodiment we present three hypotheses for augmented embodied performance: the extended artistic room, the interactively enacted teacher, and the humanisation of technology.
