Certain trends in the recital of Western art music composition and performance have embraced indeterminacy through an emerging sonic aesthetic that seeks to redefine the notion of failure. From Charles Ives' adoption of bi-tonality in the early twentieth century to the ‘glitch’ movement in contemporary computer music, this article traces ways in which musicians have sought to embrace the risk for failure in performance with special attention to virtuosic instrumental music ( Cascone 2006 ; Rodgers 2003 ; Godlovitch 1998 ; Rosen 2002 ). Drawing upon the author's recent interdisciplinary practice-led research ‘Woman=Music=Desire’ (2010) and adopting a choreographic approach to the re-appropriation of musical gesture, the author explores how the risk for failure contributes to live musical experience. This discussion is then extended to the process of corporeal acquisition necessary in rehearsing and performing a piece of music which, the author suggests, results in a degree of gestural self-simulation. In this way, the performer's personal authenticity is discussed as a potential locus of failure in which the physical manifestation of emotional expression helps to determine empathetic identification between performer, spectator and instrument ( Kivy 1995 ). Drawing upon Steven Baker's notion of ‘botched taxidermy’ (2000), the author suggests that this empathetic identification creates a space in which the potential risk for failure might be considered intrinsic to conceptions of corporeality in music performance. In this way, live musical experience is posited a site of risk in which the performer, as a desiring subject, emerges as the embodiment of failure.
