Piano Sonata, op. 1

Henri Dutilleux's Piano Sonata (1947–1948) was his only piano sonata. It is dedicated to and was premiered by his wife Geneviève Joy on 30 April 1948. The Piano Sonata has since become one of the most acclaimed post-World War II works in the genre and has been championed by major pianists such as John Ogdon, Robert Levin, John Chen and Claire-Marie Le Guay. Although Dutilleux had been active as a composer for ten years when he wrote his piano sonata, he viewed it as his Opus 1, the first work that he considered up to his mature standards.
