The performance of Western notated art music is usually associated with the notions of execution, recitation, transmission, reproduction, or interpretation, relying on the existence of a commonly accepted, sedimented musical text, and on a set of stabilised conventions that regulate the communication between composer, performer, and audience. From this perspective, performance is the moment for the concrete sonic representation of an already known sound structure. This book challenges this view, proposing a different perspective, understanding performance first as a space of problematisation, not of representation. It proposes a critical stance on the diversity of the available musical sources and materials, stressing their epistemic complexity and their potential for productive reconfigurations, suggesting new modes of creatively operating with them. Moving beyond the work concept, the book presents a new image of musical works, based upon the notions of strata, assemblage, and diagram, and proposing innovative practice-based methodologies that integrate archival and musicological research into the creative process leading to a performance. This view is not primarily intended as a rejection of interpretation, but as a movement towards a space of problematisation that is situated beyond interpretation, and that might include interpretation as one component of its fabric. Thus, my effort is to push interpretation into post-interpretation. It is, however, important to make clear that post here is to be understood neither as an epochal category, nor simply as chronologically following interpretation, but rather as a rupture and a beyond that continue to entertain relationships with interpretation. It involves subjecting the traditional relationship between music and interpretation to a critical reconsideration. This critical deconstruction of interpretation creates a productive tension with representational models, which resist change, and it is a proposal for critical renderings infused by research and inventiveness. Musical practice becomes primarily a critical act, allowing performances to be critical studies of the works performed, significantly in, by, and through the means of performance itself. In this sense, performance gains a supplementary dimension, and can be thought of as an independent form of art: independent of works of music, of supposedly uncorrupted traditions, and of idealised reconstructions of past practices and instruments. Consequently, this view also argues for a new kind of performer, emancipated from authoritative texts and traditions, and open to 21 Experimentation versus Interpretation gained visibility within the musicological subfields of performance science and performance studies, at least since the 1990s. In his essay "From Experimental Music to Musical Experiment," Frank X. Mauceri (1997, 193), distinguishing between the use of the word experiment as a historical or stylistic category and its use in science, states: "Experiment is a technique by which evidence is gathered in suppor...
