Abstract

This thesis investigates the concept of interfacial scores, a distinct category of open scores that allow for alternative interpretations using substantially different performing means. Drawing on a broad range of examples, from mid-20th-century experimental traditions to contemporary practices, the research examines how interfacial scores function as mediators between composer intent and performer agency. It explores their potential to foster creativity and adaptability across varied performance contexts while highlighting their evolution to embrace diverse media and paradigms. Central to this exploration are the notions of activity, time, and space—categories systematically analysed and developed throughout the study as integral compositional elements within interfacial scores. Given that interfacial scores do not specify the exact means of performance, the thesis turns to performance theory to investigate what composers of such scores do notate. By examining the shared characteristics underlying all performing means, the study identifies the fundamental elements that guide performers in interpreting these works. Furthermore, it addresses how performance is framed, considering the interplay of context, space, and time in shaping the realisation of interfacial scores. The study is guided by four key research questions addressing the structural and conceptual foundations of interfacial scores: the specific elements composers include, the language and notational strategies they employ, the historical trajectory of these works, and the potential for systematising these approaches into a coherent framework. Through these inquiries, the thesis establishes a comprehensive taxonomy of compositional strategies, offering a practical schema for the analysis and creation of interfacial scores. Ultimately, this thesis serves as both an academic and practical resource, providing a toolbox for composers and performers to engage with interfacial scores in innovative ways. It also lays the groundwork for future research, particularly in integrating these scores with emerging technologies and interdisciplinary practices, advancing their role as a transformative medium for creative expression and analysis.
