This paper explores issues of corporeality and physicality in my approach to composition, with emphasis on consciousness of, and the creative appropriation of, relationships between performer corporeality and instrument physicality. The predominant focus is music, but I also delineate correspondences between music and modern dance, focusing on Pina Bausch's ideas about corporeality. I also discuss the social and aesthetic unfoldings achieved through awareness of corporeality and physicality in the realm of contemporary music composition, along with an analytical discussion of my piece "Emptying the Body", for amplified violoncello.
