Pierre Henry, a composer whose experiments with electronically manipulated sound helped create the style known as musique concrète and anticipated the innovations of techno, died on Thursday in Paris. He was 89.

His death was announced on social media by Le Groupe de Recherches Musicales, an organization devoted to musique concrète.

Early in his musical career, Mr. Henry abandoned notes in favor of ambient sounds — dripping water, car horns, bird calls, locomotive engines — which he manipulated with a tape recorder in surprising ways. The sounds of the human body provided the sonic material for one of his earliest compositions, “Symphony for a Solitary Man” (1950), written in collaboration with Pierre Schaeffer, considered the founder of musique concrète.

For his cantata “The Veil of Orpheus” (1953), Mr. Henry altered a human voice to produce inhuman registers, an effect that the critic Harold Schonberg, writing in The New York Times, called “not only valid but actually exciting.”
