Experimental classical is a branch of contemporary art music that treats the concert tradition as a laboratory. Composers prioritize process, discovery, and sound itself over inherited forms, using unconventional notation, new timbres, chance procedures, and technology to expand what a "classical" work can be. The style embraces extended techniques (prepared piano, bowing the piano strings, multiphonics), alternative tuning systems and microtonality, indeterminacy and open forms, graphic and text scores, live electronics and tape, and site-specific or spatialized performance. It often blurs boundaries with sound art, electroacoustic music, performance art, and minimal/process music while remaining grounded in the discipline and scale of the classical tradition.

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.
