Driven Resonator Instrument
The instrument was
built in a collaboration between luthier Pete Schmid of the Guitar Shoppe
and sound designer Richard Wixner of Another Plane Records. Pete designed
and constructed the instrument and Richard researched the initial
functioning and developed the electronics.
The DRI functions as
follows; vibrating strings are sensed by a magnetic guitar pick up. It is
connected to a power amplifier in the far resonator globe and from there to
a speaker which faces the hollow metallic neck. The speaker is capable of driving
the system into sustained acoustic feedback. A specially developed bridge
causes the two lowest strings to rasp against it in a fashion similar to the
bridges used on some Indian string instruments.
The system can be
adjusted to generate long feedback drones which produce slowly evolving
ethereal timbres. The feedback
tones can be modified by adjusting the rasping bridge position or the
amplifier gain and polarity. The natural physics of simple processes combine
to produce complex and evolving audio textures. The instrument can also be
played using a slide in a manner similar to a steel guitar.
A description of the
DRI CD reads; The haunting drones
of the Driven Resonator Instrument merge in complex patterns that mystify
the senses. A symphony of feedback and metallic resonances. Granular
synthesis is used to further process the acoustic vibrations.
The initial Driven
Resonator Instrument CD is available from the MUSIC page. "A symphony of
feedback and metallic resonances".
