Performance space may be delineated, cordoned off, set aside: marks, surfaces, structures, both planned and improvised. Activity may be confined to and conditioned by a particular area, volume or architectural feature. Or space may be organised through the displacement of the spectators by arrangements of seating: chairs randomly scattered over the area with the performers moving in and around the spectators; laid out in lines, alleys or even blocks or round the edge of an open square. All of which may mediate the nature and quality of activity.
