This piece is part of the program Auf dem Weg zu einer neuen Klangkunst and was transmitted on the 28^th of April 1966 by the GDR’s radio station Deutschlandsender. The discussion is between Gerhard Steinke and Gerhard Schwalbe, and it is the 16th and last episode of this program. The program gives an overview of the topics discussed across the 16 episodes, presenting the studios of electronic music production as a transnational collaborative scene across the divide. In the first tape, Gerhard Steinke presents the piece Moments Musicaux by Joachim Thurm and, among other things, discusses the problem of how to translate electronic music sounds into the symbolic order of music notation. The symphonic orchestra was recorded inside Saal I of the Funkhaus in Nalepastrasse in 1965 and is placed in dialogue with the electronic sounds coming from the Subharchord. Later, the piece Galilei by Siegfried Matthus is introduced. Siegfried Matthus himself is invited to present the piece, and he speaks about his role as a composer within broader structures in the GDR, including his collaboration on the piece Manifest, based on texts by Bertolt Brecht. Matthus discusses how he used the Subharchord both as a new sound generator and as a modifier and enhancer of the human voice. Based on Bertolt Brecht’s texts, the piece is one of the most challenging tensions between abstraction and realism expressed in any compositions done in the context of this experimental studio. Unfortunately, the piece is not included in this tape.
