The installation is built up by three string instruments, that are suspended at the instruments heads. The instruments are arranged in a cycle with their strings pointing to each other. Between the instruments is a horizontal mounted bicycle wheel with embedded magnets on its outer edge. The wheel is rotated by a electric stepper motor. The steel strings of the instruments vibrate, when the magnets are passing the strings without getting in tough with them. This results in a dark, floating and oscillating sound cluster. Due to the long duration of the exhibition the string tension and thus the sound of the composed sound cluster is changing. The very outpointing aspect of the installation is therefore the combination of exactly planed and organized technology and time as a unplannable issue of composition.
