Piano Trio (1914) to complete it before joining the French Army. It contains Basque, Baroque and far Eastern influences, and shows Ravel's growing technical skill, dealing with the difficulties of balancing the percussive piano with the sustained sound of the violin and cello, "blending the two disparate elements in a musical language that is unmistakably his own," in the words of the commentator Keith Anderson. Ravel's four chamber works composed after the First World War are the Sonata for Violin and Cello (1920–22), the "Berceuse sur le nom de Gabriel Fauré" for violin and piano (1922), the chamber original of Tzigane for violin and piano (1924) and finally the Violin Sonata (1923–27). The two middle works are respectively an affectionate tribute to Ravel's teacher, and a virtuoso display piece for the violinist Jelly d'Arányi. The Violin and Cello Sonata is a departure from the rich textures and harmonies of the pre-war Piano Trio: the composer said that it marked a turning point in his career, with thinness of texture pushed to the extreme and harmonic charm renounced in favour of pure melody. His last chamber work, the Violin Sonata (sometimes called the Second after the posthumous publication of his student sonata), is a frequently dissonant work. Ravel said that the violin and piano are "essentially incompatible" instruments, and that his Sonata reveals their incompatibility. Sackville-West and Shawe-Taylor consider the post-war sonatas "rather laboured and unsatisfactory", and neither work has matched the popularity of Ravel's pre-war chamber works. Recordings Ravel's interpretations of some of his piano works were captured on piano roll between 1914 and 1928, although some rolls supposedly played by him may have been made under his supervision by Robert Casadesus, a better pianist. Transfers of the rolls have been released on compact disc. In 1913 there was a gramophone recording of Jeux d'eau played by Mark Hambourg, and by the early 1920s there were discs featuring the Pavane pour une infante défunte and Ondine, and movements from the String Quartet, Le tombeau de Couperin and Ma mère l'Oye. Ravel was among the first composers who recognised the potential of recording to bring their music to a wider public, and throughout the 1920s there was a steady stream of recordings of his works, some of which featured the composer as pianist or conductor. A 1932 recording of the G major Piano Concerto was advertised as "Conducted by the composer",
