Clara Schumann Wieck learned to compose, and from childhood to middle age she produced a good body of work. Clara wrote that "composing gives me great pleasure... there is nothing that surpasses the joy of creation, if only because through it one wins hours of self-forgetfulness, when one lives in a world of sound".

As she grew older, however, she became more preoccupied with other responsibilities in life and found it hard to compose regularly,
