Editing Pierre Schaeffer (section)

=== Groupe de Recherche de Musique Concrète ===
In 1949, Schaeffer met the percussionist-composer [[Pierre Henry]], with whom he collaborated on many compositions, and in 1951, he founded the ''Groupe de Recherche de Musique Concrète'' ('''GRMC''') in the French Radio Institution.<ref name="120years">{{cite web |url=https://120years.net/the-grm-group-and-rtf-electronic-music-studio-pierre-schaeffer-jacques-poullin-france-1951/ |title=The 'Groupe de Recherches Musicales' Pierre Schaeffer, Pierre Henry & Jacques Poullin, France 1951 |date=26 December 2013 |access-date=2022-02-28}}</ref> This gave him a new studio, which included a [[tape recorder]]. This was a significant development for Schaeffer, who previously had to work with [[phonograph]]s and [[Turntablism|turntables]] to produce music.<ref>{{Cite journal|last=Teruggi|first=Daniel|date=2007|title=Technology and musique concrète: the technical developments of the Groupe de Recherches Musicales and their implication in musical composition|url=https://www.cambridge.org/core/journals/organised-sound/article/abs/technology-and-musique-concrete-the-technical-developments-of-the-groupe-de-recherches-musicales-and-their-implication-in-musical-composition/8832D40838033A9B6743648DD373DC97|journal=Organised Sound|language=en|volume=12|issue=3|pages=213–231|doi=10.1017/S1355771807001914|s2cid=37881462|issn=1469-8153}}</ref> Schaeffer is generally acknowledged as being the first composer to make music using [[magnetic tape]].{{citation needed|date=February 2022}} His continued experimentation led him to publish ''[[À la Recherche d'une Musique Concrète]]'' (French for "''In Search of a Concrete Music''") in 1952, which was a summation of his working methods up to that point. His only opera, ''Orphée 53'' ("''Orpheus 53''"), premiered in 1953.<ref name="120years" />

Schaeffer left the GRMC in 1953 and reformed the group in 1958 as the ''Groupe de Recherche Musicale[s]'' (GRM) (at first without "s", then with "s").

In 1954 Schaeffer founded traditional music label [[Ocora]] ("Office de Coopération Radiophonique") alongside composer, pianist, and musicologist [[Charles Duvelle]], with a worldwide coverage in order to preserve African rural soundscapes. Ocora also served as a facility to train technicians in African national broadcasting services.

Over the years, Schaeffer mentored a number of students who went on to have successful careers, including [[Éliane Radigue]] and the young [[Jean Michel Jarre]], who called his mentor the first [[disc jockey]].<ref>{{cite web |title=Electronic Vibrations: Ein Sound erobert die Welt |language=de |trans-title=Electronic Vibrations: A sound conquers the world |date=2022-10-19 |work=WDR Klassik |publisher=[[Westdeutscher Rundfunk]] |at=8:00-8:50 |url=https://www.ardmediathek.de/video/wdr-klassik/electronic-vibrations/wdr/Y3JpZDovL3dkci5kZS9CZWl0cmFnLWE5ZmY3Y2M3LTRiMDgtNDkwYy04ZmE4LTczNWJiYjBhODQ3YQ |access-date=2022-10-18}}</ref> His last "''étude''" (''study'') came in 1959: the "''Study of Objects''" (''Études aux Objets'').
