Abstract

Author’s variants: Invenzioni su una voce by Bruno Maderna
The analogue audio documents, containing the Electronic works of the second half of the XX Century, are often the result of a transmission process whose phe-nomenology, although it presents some peculiarities, shows analogies with the tex-tual tradition. In this context, Dimensioni II. Invenzione su una voce by Bruno Mad-erna is an interesting case study: the more than twenty reviewed sources, which are different for duration, content, and recording format; the existence of at least five author’s variants; the many relations among the Helm’s text, the Berberian’s per-formance, the electronic elaborations, and the tape editing process require edition criteria able to render the tradition of the work in its complex articulation. This paper gives a detailed analysis of the audio sources of Invenzione su una voce, based on a deep knowledge of the electronic “writing system”, by mean of which the work has been generated.
