具体音乐 （法文：Musique concrète）1948年由Pierre Schaeffer提出，同时公演了第一步具体音乐作品《铁路上的练习曲》（Etude aux Chemins de Fer）。 是电辅音乐的前身。后来又被Francois Bayle诠释为纯听觉的音乐（Musique Acousmatique ）。 Pierre Schaeffer对何为具体音乐的诠释是这样的“以往的音乐非具体的是指作曲家将音乐转换成作曲符号，写在乐谱上，由音乐家识谱后演奏才产生音乐。可是乐谱不能发声，只是传达音乐的载体，对音乐的诠释是抽象的符号，而不是音乐本身。具体音乐直接将声音录制，直接在声音上进行创作，听到的便是声音的全部面貌，不再需要符号等抽象的工具来过渡，创作手法本身便是具体的。”

Musique concrète (French pronunciation: ​[myzik kɔ̃.kʁɛt], meaning "concrete music") is a genre of electroacoustic music that is made in part from acousmatic sound, or sound without an apparent originating cause. It can feature sounds derived from recordings of musical instruments, the human voice, and the natural environment as well as those created using synthesizers and computer-based digital signal processing. Compositions in this idiom are not restricted to the normal musical rules of melody, harmony, rhythm, metre, and so on. Originally contrasted with "pure" elektronische Musik (based solely on the production and manipulation of electronically produced sounds rather than recorded sounds), the theoretical basis of musique concrète as a compositional practice was developed by Pierre Schaeffer, beginning in the early 1940s.
