L’esperienza della musica elettronica e la sperimentazione di una forma aperta: scrittura per gruppi e percorsi esecutivi nel Klavierstück V di Karlheinz Stockhausen

For Stockhausen, the years between 1952 and the early 60s was a period of experimentation as regards both form and serial structures. Such turning point was reasonably in uenced by his contemporary explorations in electronic music, the ones which opened his eyes on renewed horizons of multi-levelled serial structuring for the manifold musical parameters. Robin Maconie has noted in that respect that Klavierstücke V-VIII, while maintaining their character as “studies”, are different from the first series (I-IV) for their abandoning an abstract formal organisation, as well as their marked orientation towards more tangible features, such as sonority, temporal unfolding, and quality of listening. However, in those years his interest did involve not only the “non-quantifiable” parameters of writing and performance, but also the overcoming of the received rhetoric-formal principles of “beginning-development-end”.
This article focuses in particular on Klavierstück V to understand whether the role played by parameters derived from experiences in electronic music maintains, on an overall formal level, the desired distance from any kind of traditional and/ or processual formal conception. The analysis rests on a close scrutiny of both the score and real performances by Aloys Kontarsky, Vanessa Benelli Mosell, and Maurizio Pollini. At the same time, a detailed investigation of the group writing and the overall form of the piece allows us to identify a few “performance paths” marked by specific trends in parameters, including choices in tempo and dynamics.
