Ravel was never so assiduous a student of the piano as his colleagues such as Viñes and Cortot were. It was plain that as a pianist he would never match them, and his overriding ambition was to be a composer. From this point he concentrated on composition. His works from the period include the songs "Un grand sommeil noir" and "D'Anne jouant de l'espinette" to words by Paul Verlaine and Clément Marot, and the piano pieces "Menuet antique" and "Habanera" (for four hands), the latter eventually incorporated into the "Rapsodie espagnole". At around this time, Joseph Ravel introduced his son to Erik Satie, who was earning a living as a café pianist. Ravel was one of the first musicians – Debussy was another – who recognised Satie's originality and talent. Satie's constant experiments in musical form were an inspiration to Ravel, who counted them "of inestimable value".
