Radio interference, traditionally a problem in audio, can be used to our advantage. By means of the Thereglyph instrument I would like to introduce to circuit-bending a concept I call radiopool.
While Leon’s Theremin looks to onboard RF generation and sounds the same played anywhere, immersing a radiopool instrument to various depths within the RF field (the radiopool) yields changing results… similar to differing the length of the air column within a flute.
Here I’m playing the Thereglyph within the radiopool of a plasma globe – sometimes touched, sometimes not. For more info on this instrument and building one yourself, check-out my flickr gallery:
