Editing Musique concrète (section)

===Club d'Essai and ''Cinq études de bruits''===
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{{cn|date=April 2024}} 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<ref name="Palombini-1993-p14"/> and on 5 October 1948 the results of his initial experimentation were premiered at a concert given in Paris.<ref>{{harvp|Chion|1983}}</ref> Five works for [[phonograph]] – known collectively as ''[[Cinq études de bruits]]'' (Five Studies of Noises) including ''Étude violette'' (''Study in Purple'') and ''Étude aux chemins de fer'' (Study with Railroads) – were presented.
