This installation is a wall-mounted, interactive, electro-acoustic, generative musical automata, controlled by an Arduino that drives servo-controlled shakers, electromagnetic buzzers, and a three-color LED. Environmental inputs from light and temperature shape the large-scale generation of dynamic, generative rhythms and textures. The Stillchime works are indoor wind chimes, providing hours of subtle, constantly changing aural ambience.
This work moves through three contrasting sections. Variations in density and tension, formed by contrasts in speed, continuity, and gesture, are the focus. Performers vary control between direct articulations, generative textures, and improvisatory gestures.
This piece was premiered and realized by students of 21M.380, Live Electronics Performance Practices, a course taught by the composer and offered by the MIT Music and Theater Arts section. This is a live recording of a performance.
Textural contrast and density are critical attributes of this piece. Heterophony is used as a context for polyrhythm and polytexture.
The performers are divided into three groups. The large-scale form is organized into a sequence of timed scenes, defined for each group by textual instructions and programmed sound sources and systems. The performers, however, are constantly improvising: they are given both direct performative control and higher-level process control. Improvisation is combined with numerous levels of algorithmic control, from shaping low-level stochastic synthesis to manipulating and combining high-level dynamic patterns. Each performer uses only a dual-analog gamepad, the interface controlling multiple sound sources and changing its functionality for each scene of the work.
This work is designed to be open and portable. The complete cross-platform control and synthesis system, implemented as part of the Martingale Pure Data library, is open source and distributed freely. Numerous varieties of dual-analog gamepads are supported. Audio samples used in this work were obtained from The Freesound Project, and are licensed under the Creative Commons Sampling Plus 1.0 License.
