The Studio d'Essai, later Club d'Essai, was founded in 1942 by Pierre Schaeffer, played a role in the activities of the French resistance during World War II, and later became a center of musical activity.
In 1942 the French composer and theoretician Pierre Schaeffer, began his exploration of radiophony when he joined Jacques Copeau and his pupils in the foundation of the Studio d'Essai de la Radiodiffusion Nationale. The studio originally functioned as a center for the Resistance movement in French radio, which in August 1944 was responsible for the first broadcasts in liberated Paris. It was here that Schaeffer began to experiment with creative radiophonic techniques using the sound technologies of the time. 
It was from d'Essai that Schaeffer successfully recorded his first work, which itself appeared on Dix ans d'essais radiophoniques du studio au Club d'Essai: 1942–1952, a compilation of his personal concrète, along with many other artists' experimental pieces, released later in his life.  The compilation has since become valued as a notable publication of the experimental music genre.[ according to whom? ]
Following Schaeffer's work with Studio d'Essai at Radiodiffusion Nationale during the early 1940s he was credited with originating the theory and practice of musique concrète. The Studio d'Essai was renamed Club d 'Essai de la Radiodiffusion-Télévision Française  in 1946 and in the same year Schaeffer discussed, in writing, the question surrounding the transformation of time perceived through recording. The essay evidenced knowledge of sound manipulation techniques he would further exploit compositionally. In 1948 Schaeffer formally initiated “research in to noises” at the Club d'Essai  and on 5 October 1948 the results of his initial experimentation were premiered at a concert given in Paris.  Five works for phonograph (known collectively as Cinq études de bruits —Five Studies of Noises) including Etude violette (Study in Purple) and Etude aux chemins de fer (Study of the Railroads), were presented.
Musique concrète is a type of music composition that utilizes recorded sounds as raw material. Sounds are often modified through the application of audio effects and tape manipulation techniques, and may be assembled into a form of montage. It can feature sounds derived from recordings of musical instruments, the human voice, and the natural environment as well as those created using synthesizers and computer-based digital signal processing. Compositions in this idiom are not restricted to the normal musical rules of melody, harmony, rhythm, metre, and so on. It exploits acousmatic listening, meaning sound identities can often be intentionally obscured or appear unconnected to their source cause.
Pierre Henri Marie Schaeffer was a French composer, writer, broadcaster, engineer, musicologist and acoustician. His innovative work in both the sciences—particularly communications and acoustics—and the various arts of music, literature and radio presentation after the end of World War II, as well as his anti-nuclear activism and cultural criticism garnered him widespread recognition in his lifetime.
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.
Acousmatic sound is sound that is heard without an originating cause being seen. The word acousmatic, from the French acousmatique, is derived from the Greek word akousmatikoi (ἀκουσματικοί), which referred to probationary pupils of the philosopher Pythagoras who were required to sit in absolute silence while they listened to him deliver his lecture from behind a veil or screen to make them better concentrate on his teachings. The term acousmatique was first used by the French composer and pioneer of musique concrète Pierre Schaeffer. In acousmatic art one hears sound from behind a "veil" of loudspeakers, the source cause remaining unseen. More generally, any sound, whether it is natural or manipulated, may be described as acousmatic if the cause of the sound remains unseen. The term has also been used by the French writer and composer Michel Chion in reference to the use of off-screen sound in film. More recently, in the article Space-form and the acousmatic image (2007), composer and academic Prof. Denis Smalley has expanded on some of Schaeffers' acousmatic concepts. Since the 2000s, the term acousmatic has been used, notably in North America to refer to fixed media composition and pieces.
Acousmatic music is a form of electroacoustic music that is specifically composed for presentation using speakers, as opposed to a live performance. It stems from a compositional tradition that dates back to the introduction of musique concrète in the late 1940s. Unlike musical works that are realised using sheet music exclusively, compositions that are purely acousmatic often exist solely as fixed media audio recordings.
Michel Chion is a French film theorist and composer of experimental music.
Surrealist music is music which uses unexpected juxtapositions and other surrealist techniques. Discussing Theodor W. Adorno, Max Paddison defines surrealist music as that which "juxtaposes its historically devalued fragments in a montage-like manner which enables them to yield up new meanings within a new aesthetic unity", though Lloyd Whitesell says this is Paddison's gloss of the term. Anne LeBaron cites automatism, including improvisation, and collage as the primary techniques of musical surrealism. According to Whitesell, Paddison quotes Adorno's 1930 essay "Reaktion und Fortschritt" as saying "Insofar as surrealist composing makes use of devalued means, it uses these as devalued means, and wins its form from the 'scandal' produced when the dead suddenly spring up among the living."
Pierre Georges Henry was a French composer, considered a pioneer of musique concrète.
Éliane Radigue is a French electronic music composer. She began working in the 1950s and her first compositions were presented in the late 1960s. Until 2000 her work was almost exclusively created with the ARP 2500 modular synthesizer and tape. Since 2001 she has composed mainly for acoustic instruments.
