Flow and Form as Modulation: Henri Pousseur's 8 Études Paraboliques and the Transformation of Electronic Music

This paper examines 8 Études Paraboliques (1972/73) by Henri Pousseur as the articulation of a different electronic modernity, grounded in continuous modulation rather than discrete sound objects or serial parameter control. Situating the work within—and beyond—the traditional Paris–Cologne dichotomy of postwar electroacoustic music, the study argues that the Études propose an alternative ontology of sound in which form emerges as a dynamic trajectory within a relational, oscillatory field. Drawing on historical documentation from the WDR Studio in Cologne, the paper reconstructs the technical and institutional conditions that enabled this approach, emphasizing the role of voltage-controlled synthesis, empirical listening practices, and the deliberate absence of a score. The cycle is further interpreted as a cybernetic system, characterized by feedback, nonlinear behavior, and emergent form, in which compositional agency is distributed across interacting processes. Building on the framework of spectral semiotics, the paper demonstrates how musical meaning in the Études arises through enacted, temporal experience rather than representation or symbolic encoding. By integrating historical analysis, systems theory, and phenomenological semiotics, the study repositions Pousseur’s Études Paraboliques as a foundational model for understanding electronic music as a modulating reality—anticipating contemporary practices in modular synthesis, live electronics, and generative sound systems.
