Ravel drew on many generations of French composers from Couperin and Rameau to Fauré and the more recent innovations of Satie and Debussy. Foreign influences include Mozart, Schubert, Liszt and Chopin. He considered himself in many ways a classicist, often using traditional structures and forms, such as the ternary, to present his new melodic and rhythmic content and innovative harmonies. The influence of jazz on his later music is heard within conventional classical structures in the Piano Concerto and the Violin Sonata.
