In the metal arch, which also reflects the optical refractions of the undulating water surface, various frequency ranges are filtered from the deeper-lying, rushing sounds of the Danube. Through the searching, scanning, listening movements of head and body, the person wanders in the frequency fields of the vaulted ceiling. A dance-like dialogue with the Danube floating above one.

Purchased by the City of Donau-eschingen, the installation is shown from May to October.
