GRM was one of several theoretical and experimental groups working under the umbrella of the Schaeffer-led Service de la Recherche at ORTF (1960–1974). Together with the GRM, three other groups existed: the Groupe de Recherches Image GRI, the Groupe de Recherches Technologiques GRT and the Groupe de Recherches which became the Groupe d'Etudes Critiques. Communication was the one theme that unified the various groups, all of which were devoted to production and creation. In terms of the question "who says what to whom?" Schaeffer added "how?", thereby creating a platform for research into audiovisual communication and mass media, audible phenomena and music in general (including non-Western musics). At the GRM the theoretical teaching remained based on practice and could be summed up in the catch phrase do and listen.
