Vanishing Trajectories in
collaboration with Keiichi Tanaka (live lasers, various optical devices, and video)
Vanishing Trajectories (2015) is an audiovisual work consisting of music, live lasers, optical filters, various light effects, and video. It comprises 6 sections and the music of each section is generated by a Lindenmayer system.
The music begins with the 12-tone aggregate that corresponds to the opening blackout. As the music unfolds, synchronizing with the formation and the transformation of visual patterns, the 12-tone aggregate starts evolving, gradually forms patterns of continuously transforming pc-sets, and in the end grows into the patterns found in the second and the third sections. All the transformations of the pc-sets and the formation of melodic patterns are strictly regulated by L-systems. The music is entirely generated by my own Java program, in which the L-systems and all the rules for the transformations of pc-sets, voice leading, and melody formation are implemented. The Java program generated score files for RTcmix instruments of channel vocoder, table-lookup synthesis, and others written by Brad Garton, John Gibson, and Doug Scott.
The following is the live performance of the piece at NYCEMF 2017 (New York City Electroacoustic Music Festival), which took place on June 19, 2017:
Vanishing Trajectories was presented at RTcmix Festival 2017 in New York in October, 2017 together with my talk "Compositional Work with RTcmix."
Vanishing Trajectories was invited and presented at Shinyurigaoka Sogo Hospital in July, 2017 as part of Japan Cultural Olympiad - Tokyo 2020 support Program.
