Thesis title in Musical Interpretation and Composition: "Performing Space – Shaping Experience: Multimediale Strategien, Publikumserfahrungen und neue Zugänge in der experimentellen elektronischen Musik" (defense on June 16th 2026)
As part of his PhD thesis, Lorenz Rommelspacher, a PhD student at the GLAREAN College, is giving a graduation concert.
The starting point for S_4_S is the observation that absolute silence does not exist. Silence is understood here as an ‘absence of definite action’: a state that arises when sounds are not actively produced, yet attention remains.
Philosophically and epistemologically, the work draws on the ideas of John Cage and Pauline Oliveros, whilst shifting their questions into its own compositional practice.
S_4_S is fully composed and follows a clear dramaturgical arc. The compositional framework defines temporal sequences, states of listening and transitions between intensification and reduction. At the same time, the sonic outcome remains open-ended: the musical material arises exclusively from live-sampled and electronically transformed sounds generated during the performance.
The audience and the performance space thus become central sources of sound. Sounds made by those present, atmospheric sounds from outside, and random acoustic events are captured in real time, processed and integrated into the musical structure. Each performance thus produces its own, unrepeatable sonic outcome.
S_4_S thus understands composition as the shaping of conditions: it is not individual sounds that are predetermined, but the situation in which listening itself becomes a musical act and the relationship between silence, noise and music is continuously reshaped.
