The basic rule of acoustics for open-air stages, ‘what you see is what you hear’ serves as a cue to explore affinities between perspective and acoustic space. The topography of the existing depression – the ‘Große Senke’ – was emphasized by modeling the terrain. Artificial hillocks are created by further excavating the depression and subsequently redistributing the soil at its perimeter, thus creating the auditorium tiers. Clearly distinguished from the natural terrain by their geometry, stage and auditorium nonetheless merge fluidly with the topography of the site.
