Who was Schumann thinking of in the opening of the Fantasy?

Never one for disguising his emotions, Robert Schumann wore his heart on his sleeve and his music reflects his joy at being alive – and of being in love. His Fantasie in C, composed in 1836, is a remarkable display of soul-bearing, a piece imbued with passionate and unresolved longing, and the heart-fluttering panoply of emotions from ecstasy to agony which being in love provokes. It was written during a particularly long separation from his beloved Clara Wieck, at a time when their future together was far from certain.
