As far as the style is concerned our work is part of the group called "Einknüpfungen" (Knottings), made as of 1953. They emphasize the haptic-rhythmical aspect. In this composition Zangs groups pebbles on top of one another and side by side, fixating them in the coarse canvas by means of a string. The works interpretation is implied by the structural arrangement and yet remains open, so that the work's different aspects appear only through the observer's subjective perception. [EL]
