[...] At the centre of the room, a »Jubeltöne« zither waits for the visitor. And speaks to him/her. Through a loudspeaker built into the sound hole, the Swiss zither soloist Lorenz Mühlemann tells us many things about the zither. His flow of words can be briefly stopped only by plucking the zither's strings.
In addition, visitors – depending on how they play the instrument – trigger zither music that itself reacts to their playing. The interactivity between player and storyteller is of essence. After a while, the played phrases return, drown out the storyteller's torrent of words, and mix with new kinds of abstract zither sounds that are generated in real time – again dependent on how the visitor plays. What develops is a multilayered collage that contains both informative and documentary material as well as exciting sounds – a kind of installational radio feature.
