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.

Electroacoustic music is a broad art-music tradition that integrates recorded acoustic sound and electronically generated or processed sound into coherent musical works. It privileges timbre, gesture, texture, and spatialization over conventional melody-and-harmony song forms, often employing tape manipulation, synthesis, live electronics, and computer-based signal processing. Works are frequently composed for fixed media (stereo or multichannel loudspeakers) and may also involve live performers who are transformed in real time. Concert presentation typically emphasizes spatial diffusion and immersive listening, and the repertoire spans concert works, radio pieces, installations, and soundscape compositions.

Electronic is a broad umbrella genre defined by the primary use of electronically generated or electronically processed sound. It encompasses music made with synthesizers, drum machines, samplers, computers, and studio/tape techniques, as well as electroacoustic manipulation of recorded or synthetic sources. The genre ranges from academic and experimental traditions to popular and dance-oriented forms. While its sonic palette is rooted in electricity and circuitry, its aesthetics span minimal and textural explorations, structured song forms, and beat-driven club permutations. Electronic emphasizes sound design, timbre, and studio-as-instrument practices as much as melody and harmony.
