„Quintenzirkel mit Ölbaum“
The sculpture „Circle of Fifths“ consists of 13 modular lighting objects that are joined together to form a circular bench. If a visitor is at the center of the banking segments, sounds (depending on where in the Bank, he sits) a tone from the circle of fifths, ascending: C, G, D, A, E, H, Gifts, In, As, It, B, F, C
when all modules are „centered“ occupied, then the visitor hears a polyphonic sound from the thirteen different tones; in partial occupation of the bank different melodious or rather grotesque perceived pitch combinations are possible – depending on configuration, and seating position of the visitors.
