thumb|left|April from the manuscript of Fanny Hensel's Das Jahr (illustration by Wilhelm Hensel) Most of Hensel's work after her marriage was on a small scale, songs and piano pieces. In 1831 for the first birthday of her son Sebastian, she created a cantata, the Lobgesang (Song of Praise). Two other works for orchestra, soloists and choir were written in that year, Hiob (Job) and an oratorio in sixteen sections, Höret zu, merket auf (Listen and take note). In 1841 she composed a cycle of piano pieces depicting the months of the year, Das Jahr (The Year). The music was written on tinted sheets of paper and illustrated by her husband, with each piece accompanied by a short poem. The writer Kristine Forney has suggested that the poems, artwork and coloured paper may represent the different stages of life, with others suggesting they represent her own life. In a letter from Rome, Fanny described the process behind composing Das Jahr:I have been composing a good deal lately, and have called my piano pieces after the names of my favourite haunts, partly because they really came into my mind at these spots, partly because our pleasant excursions were in my mind while I was writing them. They will form a delightful souvenir, a kind of second diary. But do not imagine that I give these names when playing them in society, they are for home use entirely. After Das Jahr her only large-scale work was her Piano Trio Op. 11 of 1847.
