A term created by Pierre Schaeffer in 1948 to describe his new music, which started from the concrete sound material, from heard sound. Schaeffer wanted people to ignore the source and cause of the concrete sounds, and instead focus upon the musicality of sounds. He wanted to encourage Musical Listening for all sounds.
Many early works of Musique Concrète, due to the unsophisticated tools on offer, could be listened to both in terms of their sources as well as their musical qualities.
