Rekonstruktion für Chor is a composition for senior women's choir and live electronics that explores memory as a bodily, sonic, and collective process. The project brings choral practice together with AI-based reconstruction models and asks how human and technical memory might be understood not as opposites but as interwoven forms of remembering.

The piece was developed in close collaboration with a senior women's choir from Berlin and has a strong community dimension: conversations about ageing, remembering, and time entered the work as much as the concrete rehearsal practice itself. Out of the rehearsals grew a continually expanding corpus of choral recordings — a "sonic memory" that comprises both systematic vocal material and individual, biographically inflected sounds.

The live electronics work with this corpus and with associative AI models that can complete fragmentary patterns and find their way back to stored states. Musically, memory becomes perceptible as a process of approximation, stabilization, transformation, and disappearance. The score is conceived less as a fixed notation than as an open system of collective listening and coordination.

What emerges is a performative space of memory in which individual voices, collective practice, and algorithmic procedures intertwine into a shared musical temporality.

Premiered by Chorwerkstatt Berlin on November 16, 2025, at Radialsystem Berlin.
