This major exhibition organised inside the Kunstlerhaus featured all kinds of materials: paintings and etchings, sculptures, musical instruments, musical scores, correspondence, everyday objects and period relics. It also hosted a reconstruction of six of the composer´s opera sets. It was designed like a guided tour constructed out of long parallel walls fitted with glass windows. These windows had wooden reticular frames with channels inside them for playing the music. Indeed, a soundtrack of Mozart´s works accompanied the entire tour. The lighting appliances were also attached to these structures. These appliances, specially designed and manufactured in small numbers, were made of copper elements supporting a cardan joint to make the sources as adjustable as possible. This simple, mobile appliance was the main feature of all the exhibition lighting on both the walls and windows.
