Schumann’s piano music is very well known. Although he had to give up his career as a pianist his wife Clara played his pieces and helped them to become famous. Many of his piano works are collections of short pieces, each with a title e.g. "Papillons" ("Butterflies"), "Davidsbündlertänze", "Carnaval". Schumann was thinking of carnival celebrations when he wrote these pieces. The Davidsbündler was a group of people Schumann belonged to who did not like the “Philistines” (people who did not enjoy good music, named after the Philistines in the Bible) In "Carnaval" the two sides of Schumann’s personality are represented by Florestan and Eusebius. Schumann's manic depression (the happy and the tragic moods that he had) are heard side by side in his music. Other piano works include, "Kreisleriana","Album for the Young" which has some quite easy pieces like "Soldier’s March" and the popular "Scenes from Childhood" with its famous "Träumerei" ("Dreaming"). There are also longer works for piano: 3 sonatas, a Toccata and a Phantasie.
