Music concrête is a type of music that sprang directly out of the evolution of music technology. As a throwback to classical music being inspired by poetic forms, music concrête has its roots in the 1920s Surrealist literary practice of cut-up and fold-in composition.
In cut-up, writers would physically cut up existing pieces of literature and rearrange the order of the phrases and words, whereas in fold-in compositions, a group of writers would write random phrases, one at a time, on a piece of paper, folding the paper over after each turn so that the next writer couldn't see what the previous writer had written.
