Compositional strategies of spatialization in Terretektorh by Iannis Xenakis

Abstract

Spatialization refers to the compositional use of the physical, acoustical, and perceptual dimensions of sound (Harley, 1994). It encompasses both the localisation of sound sources and the perception of their position within a given environment. Spatial sound is shaped by multiple parameters, including dynamics, density, texture, and timbre (Kermit-Canfield, 2013). Iannis Xenakis occupies a central position among composers engaged with spatial music. Spatiality functioned as a fundamental compositional principle in his work, informed by his dual background as an architect and a musician (Hofmann, 2005). Terretektorh (1966) exemplifies this approach: musicians are distributed in a large circle, with audience members interspersed among them, transforming the performance space into an immersive sonic environment. The present study, grounded in an analytical model–based approach, examines the compositional techniques through which Xenakis generates a dynamic spatial environment, particularly through the localisation of instruments and the organisation of musical textures. The finding demonstrates that the circular distribution of sound sources and the transfer of musical material between instrumental groups create the perceptual illusion of sound motion and rotation. In this context, spatial rotation and motion are understood not as literal physical movements but as metaphorical and perceptual constructs that emerge from compositional processes. The study further clarifies the concepts of rotation and trajectory in Terretektorh, using it as an analytical model. It also reveals how Xenakis redefines conventional musical parameters. The finding demonstrates that the compositional processes exemplify spatial sounding as a form-generating phenomenon that fundamentally shapes musical structure, performance practice, and listener perception. The methodology draws on established scholarship in the field and is structured around four analytical categories: spatial distribution, motion and rotation, texture, and perceptual dimension. These categories are examined through integrated score-based, sound-based, and form-based analyses. The methodology and findings contribute to a more systematic understanding of spatial composition as a primary musical parameter in contemporary immersive practices. The significance of this research lies in clarifying key concepts in compositional techniques, establishing a conceptual vocabulary for analysing spatial sound, and positioning Terretektorh as a critical reference for both analytical inquiry and compositional development.
