A "musical-literary afternoon" with compositions by J.S.Bach and texts by Georg Kreisler, among others, in the senior citizens' center at the Bürgerpark. The songs are played on the campanula, a cello-like instrument.
Developed in 1989 by Helmut Bleffert, the Campanula has 16 sympathetic strings in addition to the 4 strings of the cello. These are not played, but resonate and thus amplify the overtones. This creates a long reverberation.
