Musique concrète
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. His work laid the foundations of the Musique concrète. This technique involved editing together recorded fragments of natural and industrial sounds. The first pieces of "musique concrète" in Paris were assembled by him, who went on to collaborate with Pierre Henry.
