The Topological Model in the Works of Yuasa Jōji

Abstract

The oeuvre of Japanese composer Yuasa Jōji holds a singular place in the contemporary musical landscape. From the artist collective Jikken Kōbō, in which he took part during the 1950s, to his later pieces for large orchestra, and through his innovative electroacoustic and mixed-music, Yuasa single-handedly explored a vast number of musical issues across the twentieth century. This article aims to shed a new light on the composer’s substantial musical output through his interest in topological theories. It will be a question of showing through examples, the different outcomes of the application of this mathematical model in the musical domain, all the while demonstrating how it takes place within his nexus of influences, as a centre towards which many other of Yuasa’s interests converge.
