スティーヴ・ライヒの「プロセスとしての音楽」 : ポストミニマリズム美術との連関

抄録

Steve Reich (1936-), in his essay "Music as a Gradual Process" (1968), wrote that "a compositional process and a sounding music […] are one and the same thing." His aesthetic creed of "perceptible processes," indicated in these words, is known as the basic idea of minimal music. Although minimal music has been considered a counterpart of minimal art, this essay first appeared in the exhibition catalogue of "Anti-Illusion: Procedures/Materials" (Whitney Museum of American Art, 1969), an exhibition recognized as a threshold of postminimalism in the plastic arts. In this paper, I would like to clarify a linkage between Reich's music and postminimalist art in view of his involvement in the "Anti-Illusion" show. The theme of the "Anti-Illusion" show was to refocus on the process of making art. By emphasizing the processes and materials of the works, the participating artists tried to deny illusion and expose the reality of art. Among these works, Reich performed his Pendulum Music, in which he made the sounding process visible as microphones' swinging. This piece clearly demonstrates that Reich's claim in "Music as a Gradual Process" was propounded in connection with postminimalist art as an attempt to disclose musical processes and reveal the real.
