Risset: Songes / Passages / Computer Suite from Little Boy / Sud

Electroacoustic composition is a branch of art music that uses microphones, tape, analog and digital synthesis, and studio processing to create works in which timbre, texture, space, and transformation are primary musical parameters. Emerging from the post‑war laboratory and broadcast studio, it brings together recorded real‑world sounds (musique concrète), purely electronic tones (elektronische Musik), and later computer processing. Works may be fixed‑media pieces diffused over multi‑speaker systems, or live‑electronics that transform acoustic sources in real time. Rather than traditional melody and harmony, form is often built from sound objects, spectral evolution, gesture, and spatial motion.
