The filmmaker and artist Mara Mattuschka and the composer and musician Elisabeth Schimana have a rendezvous. Mara Mattuschka hears nothing and Elisabeth Schimana sees nothing. They have, however, agreed on a common line, on a text to be written together that, like a score, will serve as this common line for a 50-minute AV performance. The text is about strings that oscillate in the body, tubes through which the body receives nourishment and air, skins that are made to vibrate like a membrane.
