The City Plays the Tuning Tube

The tuning tube generates an overtone series in response to the sounds around it. Low sounds stimulate the fundamental of the tube which is based on its length. Higher sounds stimulate higher overtones. Noise is rejected. In this way sounds are reduced to the harmonic ratios of the overtone series, noise becomes harmony. This harmony is picked up by a microphone placed at a harmonic node within the tube. The result is like a digeridu played by a city, a shifting chanting sound which organically changes with whatever is going on around it. People tend to find listening to the harmonically altered city noise less fatiguing, even meditative. The emotional landscape is altered. What you hear changes what you see.
