Pierre Schaeffer was a French composer and musicologist, born on August 14, 1910, and known for his pioneering work in the field of electronic music. He is best recognized for developing the concept of musique concrète, which involves using recorded sounds from the environment as raw material for composition. This innovative approach transformed how music could be created and perceived. Schaeffer's work laid the foundation for many modern music practices, influencing various genres and artists. He also contributed to the establishment of the Groupe de Recherches Musicales (GRM) in 1958, which became a significant center for experimental music and sound research. His legacy continues to inspire musicians and sound artists today.
