Workshop with the Fabrik Quartet at 14:30
Concert with Quatuor Diotima at 16:00

"The string clef illustrates actions on the four string parts behind the bridge,... Apart from the 'normal' bow pressure ... the flautato playing and the pressed bow stroke play an important role... The playing instructions battuto, saltando and balzando must be carefully observed in their diversity." Even this small excerpt from the four closely printed columns with "Explanations on notation and performance practice" for Helmut Lachenmann's first quartet "Gran Torso" makes it clear that it is not at all easy to bring this composer's unique notation to the string instruments. The workshop with the Fabrik Quartet and Lucas Fels gives the audience a rare insight into Lachenmann's musical text and his playing technique instructions. The Quatuor Diotima's performance of his "Reigen seliger Geister" (Round dance of blessed spirits) will also reveal the meaning of his remark "Töne 'aus der Luft gegriffen', 'Luft' aus den Tönen gegriffen".
