"Doctor Gradus ad Parnassum" is the opening piece of Debussy's piano suite "Children's Corner" (1908), composed as a humorous tribute to his daughter Chouchou. The piece playfully parodies the tedium of Clementi's Gradus ad Parnassum piano exercises, using rapid repetitive figuration and a witty blend of earnestness and irony in Debussy's characteristic Impressionist style.
