Musique concrète is a type of music composition that utilizes recorded sounds as raw material. Sounds are often modified through the application of audio signal processing and tape music techniques, and may be assembled into a form of sound collage. It can feature sounds derived from recordings of musical instruments, the human voice, and the natural environment as well as those created using sound synthesis and computer-based digital signal processing. Compositions in this idiom are not restricted to the normal musical rules of melody, harmony, rhythm, and metre. The technique exploits acousmatic sound, such that sound identities can often be intentionally obscured or appear unconnected to their source cause.

Luc Ferrari was a French composer of Italian heritage and a pioneer in musique concrète and electroacoustic music. He was a founding member of RTF's Groupe de Recherches Musicales (GRMC), working alongside composers such as Pierre Schaeffer and Pierre Henry.
