The sound sculpture CHORD refers to the concept of acoustic ecology by R. Murray Schafer, who already in the 1960s drew attention to the problem of increasing noise in urban spaces, negatively affecting the comfort of residents. The starting point for sculpture is the observation that we need a space of releasing tranquility in cities, especially today. "Chord" consist four cylinders of rusted steel, rotating around a single axis at different speeds and alternating directions of rotation. One can see in this continuous omnidirectional movement a reference to the dancing trance of dervishes. Inside each cylinder are separate speakers emitting sounds within a radius of about ten meters. The whole thing is controlled through Arduino computers and a control code specially written for this sculpture. Four compositions of the same length of about 10 minutes are stored in the Arduino's operating memory. The control code also allow random combinations of tracks from different compositions. In this way, the sculpture on the sound side morphs neatly. The idea is ultimately to create the musical equivalent of the relaxing sensations brought by the sound of the sea, a waterfall, or rain, and thus to relax and unwind. The combination of sculpture as a mobile three-dimensional visual form and musical form is intended to be a kind of symbolic space-time. A world submerged in benevolent time.
