J. A. Riedl, who lived and worked in Murnau, was a composer and a luminary of “New Music”. Since his studies at the Munich Music Academy, he was strongly influenced by Carl Orff, among others. Riedl accompanied the performances of his compositions down to the smallest detail with highly concentrated professionalism. He invented walk-in and playable sculptures made of various glass elements, the paper music sound worlds made of paper, cardboard and cardboard, and created sound poems for clapping and stomping speakers. Riedl directed the Siemens Studio for Electronic Music, among others, and the Kulturforum in Bonn from 1973 to 1983. He worked with film and theater directors such as Franz Xaver Krötz, Fritz Kortner and Edgar Reitz, but also with students, children and amateurs. Riedl worked as a curator for the “musica viva” series. The museum's depot contains the extensive components of the structures for his compositions Paper Music and "Glass Games", which were built over several days.
