Musique concrète built music from recorded real-world sounds rather than notation for instruments

In the late 1940s, French composer Pierre Schaeffer theorized and coined musique concrète — electroacoustic music built from recorded concrete (real-world) sounds rather than abstract notation for instruments. His 1948 Five Noise Studies began with Etude aux Chemins de Fer, assembled from locomotive sounds at Paris’s Gare des Batignolles station, and premiered on radio as Concert de bruits (Noise Concert) on October 5, 1948. The method treats any recorded sound as raw compositional material — it can be reversed, looped, speed-shifted, or layered. This established recorded-sound manipulation as a compositional discipline and directly ancestored electronic music production techniques including sampling.

Examples

Schaeffer’s Etude aux Chemins de Fer (1948) — locomotive sounds as music. Varèse’s Poème électronique (1957) used tape-recorded scraping, thumping and blowing. Cage and Lou Harrison scoured junkyards for tuned brake drums and flower pots for junk percussion.

Assessment

What is the core compositional claim of musique concrète? How does it differ from Beethoven using cannon sounds in Wellington’s Victory? Name the specific technique Schaeffer applied to railway sounds.
