Resonance occurs in natural systems when an object’s natural vibration frequency responds to an external stimulus of the same frequency. Resonance can investigated in terms of oscillations, vibrations, waves, fields. We are interested in social as well as sonic aspects of resonance. In social systems, resonance is opposite to alienation, and relates to the way ideas and experiences generate meaning individually and collectively. In both cases, resonance thus involves movement and temporality, and is expressed as a set of relations. Three example projects are described here – using electrical resonance, a vibrating string, and an air resonating chamber; all incorporate social aspects of resonance.
