The remarks on this subject stem from the conditions spatial works engender in the encounter with the viewer. The aim has been to provide the reader with a framework within which to place individual experiences of the works. The exhibition Spatial Works, to which this research paper is connected, exemplifies variations within spatial work. By organizing an exhibition around this context, the variations presented is fleshed out. The research preceding the exhibition has resulted in the development of a specific terminology; an articulation of different practices in installation art. Psychodramatic, Thespian, Temporal and Permutation are here seen as mannerisms of spatial works of art. The expanded significance presented in this paper is a feature of composition, as the dramatic condition characterizes the encounter between object and subject. The polyphony of information encountered by the viewer is not only created by the art work itself, but also by its signifying composition, so to say `al fresco´ of the work, of which the observer gains certainty of the pieces spatiality as well as understands of the work of art. / WIRE, Critical Writing and Curatorial Practice
