Focusing on Western theatre dance, Choreography Invisible explores the metaphysics of dances and choreographic works. It draws on a range of resources from analytic philosophy of art to develop the argument that dances are repeatable structures of action. The book also analyses the idea of the dance work in long-term historical perspective. Tracing different ways in which dances have been conceptualised across time, the book considers changing notions of authorship, fixity, persistence, and autonomy from the fifteenth century to the present day. The modern work-concept is interrogated, its relativity and contested status (particularly within contemporary dance practice) acknowledged. As the dance work disappears from contemporary discourse, what can be said about the kind of thing it is? Choreography Invisible considers the materials of dance making and the nature (and limits) of choreographic authorship. It explores issues of identity and persistence, including why distinct (and sometimes quite various) performances are still treated as performances of the same work. The book examines how dances survive through time and what it means for a dance work to be lost, considering the extent to which practices of dance reconstruction and reenactment can recuperate or reconstitute lost choreography. The focus here is dance, but the book addresses issues with wider implications for the metaphysics of art, including how the historical relativity of art practices should inflect analytic arguments about the nature of art works, and what place such works have within a broader ontology of human and natural worlds.
