Peter and the Wolf (Russian: Петя и Bолк, tr. "Pétya i volk", IPA: [ˈpʲetʲə i volk]) Op. 67, a "symphonic fairy tale for children", is a musical composition written by Sergei Prokofiev in 1936. The narrator tells a children's story, while the orchestra illustrates it by using different instruments to play a "theme" that represents each character in the story. It is Prokofiev's most frequently performed work and one of the most frequently performed works in the entire classical repertoire.
