Interactive audio-visual installation,
Shown at the LAB’s 25th Anniversary Exhibition July 31-August 29, 2009
A long string “self-oscillates” or has no visible performer, constantly sounding and evolving. The oscillations of a long string are visually manifested on a TV monitor as waves perpetually modulating. The monitor is hanging from above, shining down on the string.
Wood, steel, magnets, CRT TV, Mac Mini, custom electronics
The set is dark of a black box theater, except for two violins on white pedestals placed symmetrically about the center of the stage with spotlights on them, and a screen illuminated by reflections of water waves.
One of these violins is “self-oscillating” or has no visible performer. A violinist, dressed in white and lying down on the pedestal, performs the other violin.
The Self-Oscillating Violin (2005)
A second-hand violin is transformed into a self-oscillating system by the use of electromagnetism and a computer. Motion detectors excite long tones of oscillation. The audio vibrations of each string are transduced into surface waves of a thin layer of water on a concave mirror. The shadows of waves reflect onto the ceiling by a suspended blue flashlight.
Vibrational Matrix Series (2004-5)
A series of performance/installations utilizing vibrations in water, speakers, live Max/MSP/Jitter processing or microelectronics, feedback.
