Robert Schumann

This list of compositions by Robert Schumann is classified into piano, vocal, orchestral and chamber works. All works are also listed separately, by opus number. Schumann wrote almost exclusively for the piano until 1840, when he burst into song composition around the time of his marriage to Clara Wieck. The list is based on lists of his works, such as in the 2001 biography by Eric Frederick Jensen.
