The halo of uncertainty used to be a friend of mine (sound installation 2018)

Eight identical steel strings are mounted on a metal plate. Using short circuits the strings are heated until they start glowing. The ever-changing vibrations they produce when cooling down, get picked up by four contact microphones inside the object. The signal gets amplified and played through a loudspeaker or headphones until the strings burn out and have to be replaced.

Even though all the strings are the same, the resulting sounds differ a lot depending on the tension, curvature and their deterioration.
