The young composers of the Klangwege programme were faced with special challenges this year: the task was to create pieces for the voices of the Schola Heidelberg ensemble, who are just as familiar with renaissance capella music as with works from the 20th and 21st century. Clemens Gadenstätter supervised the students from Graz University of Music and Performing Arts to create their purely vocal compositional explorations and the singers will present  what new music the human voice can inspire at musikprotokoll.
