Is it still possible to discover “new” sounds today? The answer, according to the Berlin-based experimental collective Harmonic Space Orchestra, a unique formation of 15 “performer-composers” who research and explore tuning and the harmonic space through immersive experiences, is a resounding yes! The group, formed in 2019, will make its debut at L’Auditori with compositions by renowned sound alchemists such as James Tenney, Catherine Lamb -professor at the 2025 Mixtur Composition Workshop-, and Marc Sabat. This is a unique opportunity to experience one of today’s most innovative contemporary ensembles.

Harmonic Space Orchestra (HSO) is a Berlin-based experimental research and performance collective with Rational Intonation / extended Just Intonation at the core of its practice. Initiated by Catherine Lamb, Rebecca Lane and Marc Sabat in 2019, it has been growing and taking shape ever since, integrating an extensive network of musical relationships that have been developing in different constellations, contexts and countries for over 15 years. The collective currently consists of 15 core composer-performers who approach precisely tuned sound-forms in a pluralistic manner. The uniqueness of the ensemble emerges from practice-based research as a collective on a subject that is rarely placed as a central focus: Harmonic Space.
