a musical instrument inspired by elisha gray's "musical telgraph" one of the first electric/electronic musical instruments ever.
it's basically a relay oscillator than be "tuned" to various frequencies via midi controlled capacitors.
in the video i use a tenori-on as a midi sequencer. the video of the tenori-on is not totally in sync with the rest of the video but you should get an idea.
the sound is recorded with a self-built piezo contact mic and a coil taken from a solenoid.
