Composer's last three chamber works, written from 1915 to 1917. Cello Sonata is rich in unconventional, sometimes surrealistic effects. Violin Sonata integrates jazz influences with impressionism. Sonata for Flute, Viola and Harp sparkles with spontaneity and innovation. All are sonatas of individual charm and definite 20th-century character; all reproduced from authoritative French editions.
