Some simple paths, clearly traced with, here and there, elements of surprise and unexpected detours, “Trajectoires parallèles” is a new automatic version—the performance of the two electroacoustic instruments is controlled by computer—in six moments of “Trajectoires” (1987-88), a live electroacoustic piece for DX7(E!) and TX7 composed for the Vancouver composer/performer Sergio Barroso. By choosing a limited instrumentation and a limited sonic world—one timbre per moment—the composition focuses on sonic gestures, the articulation and animation of each timbre. It is by playing and reshaping the initial sounds that each timbre revealed its very own gestures. In general, the timbres cover a wide register region—like a cloud of sound—rather than a narrow or unique sonic height. “Trajectoires parallèles” was premiered at the SCAQ “Musique et ordinateur” concert in Montréal in November 1987. The piece was originally composed during the summer 1987 in Montréal and was rearranged and extended at the Grame studio in Lyon (France) in October 1988. JFD
