Modern performance is a contemporary classical performance practice focused on post‑war and post‑tonal music, cutting‑edge notation, and exploratory sound. It privileges close composer–performer collaboration, precision of ensemble craft, and the use of extended techniques, electronics, and non‑traditional staging.
The style grew around specialized ensembles able to realize complex rhythms, microtonality, new timbral combinations, live electronics, and spatialized setups. Scores may be conventionally notated, graphically specified, or text‑driven, and the result ranges from quiet, fragile textures to aggressive, noise‑inflected masses. Modern performance is less a single compositional language than a shared performance culture devoted to “new music” ideals of experimentation, rigor, and timbral imagination.
After World War II, the new‑music ecosystem cohered around summer courses, festivals, and radio studios that fostered a performance culture able to realize serial, pointillist, and electronic works. The Darmstadt School crystallized shared ideals of precision, new timbre, and structural innovation. Performers internalized click‑track discipline, flexible metric reading, and extended techniques, laying the groundwork for a distinct practice.
By the 1970s, permanent ensembles devoted to contemporary repertoire emerged, building fluency in complex polyrhythms, unconventional bowings and articulations, multiphonics, prepared instruments, and real‑time electronics. Recording studios and public broadcasters amplified this scene, while festivals spread the repertoire internationally.
A pluralist repertoire—post‑minimal, spectral, noise‑aesthetic, and electroacoustic—expanded the palette. Laptop performance, live processing, and mixed works (acoustic plus fixed media) became common. Conservatories trained performers specifically for new‑music skill sets (microtones, extended notation, click‑track synchronization, and chamber virtuosity).
Modern performance is now a global practice spanning concert halls, galleries, and site‑specific spaces. Ensembles commission collaboratively, circulate parts digitally, and integrate lighting, video, and spatial design. The scene balances rigor with accessibility, curating programs that juxtapose classic late‑20th‑century repertoire with premieres, and engaging audiences through talks, workshops, and multimedia formats.
