Clara Schumann (1819-1896) - Nocturne in F major Op.6 No.2 from 'Soirées Musicales' :
Clara Schumann was married to the composer Robert Schumann. She had eight children and:
often took charge of finances and general household affairs. Part of her responsibility included making money, which she did by giving concerts, although she continued to play throughout her life not only for the income, but because she was a concert artist by training and by nature. She was the main breadwinner for her family, and the sole one after Robert was hospitalized and then died, through giving concerts and teaching, and she did most of the work of organizing her own concert tours. She hired a housekeeper and a cook to keep house while she was away on her long tours. She refused to accept charity when a group of musicians offered to put on a benefit concert for her. In addition to raising her own large family, when one of her children became incapacitated, she took on responsibility for raising her grandchildren.Robert Schumann, on Clara's composing:
Clara has composed a series of small pieces, which show a musical and tender ingenuity such as she has never attained before. But to have children, and a husband who is always living in the realm of imagination, does not go together with composing. She cannot work at it regularly, and I am often disturbed to think how many profound ideas are lost because she cannot work them out.
