SWO performances are concerned with breaking the border between spectators and musicians, as well as the common restriction of the traditional formats of music (music has a beginning and an end) and its hierarchy (e.g. a classical orchestra).
SWO in ISEA invited participants to meet at a given time and place to perform together, everyone in their own manner and to their own liking. Participants were asked to either bring a sine wave generating object or make use of the provided egg-shaped sine wave generator, furnished with a loudspeaker and controllable via a potentiometer (frequency) and an on/off switch.
