Among the works of her maturer period, her church music ranks highest of all. Her oratorio "Isacco," with words by Metastasio, is her worthiest production, and met with deserved success when performed at Vienna in 1788. Besides this work, she composed two other oratorios, a successful mass, a four-part Miserere, a number of psalms for four and eight voices, with orchestral accompaniment, several motets, and many other pieces of a religious character. The list of her works does not end here, but comprises symphonies, overtures, and other orchestral numbers, including several piano concertos. Taken as a whole, her works entitle her to a worthy place among women composers of all time. Leaving the eighteenth century, the next woman composer of note is Emilie Zumsteeg. Born at Stuttgart in 1796, she soon showed that she had inherited the musical taste of her father, himself a well-known composer. On his death, six years later, the widow supported herself by keeping a music-store, where the growing daughter absorbed much knowledge of the art. Soon she began regular study, and won her way into notice by her singing and piano-playing. Her sight-reading abilities were something phenomenal, and she could play from full instrumental scores with ease. Her home became the centre of a brilliant circle, including Weber, Hummel, Lindpaintner, and poets as well as musicians. She was much prized as a teacher of piano and singing, and a personal favourite in her native city. Of her compositions, the most ambitious is an overture to the play "Die Geister Insel." She wrote also several piano pieces, among them three polonaises. But according to German authority,[7] it is her songs that have made her memory honoured. Her originality and her skill in metrical treatment have won her high praise, and many of the songs achieved wide popularity. Leopoldine Blahetka, the Austrian pianist, was one of the most prolific of women composers. Born near Vienna in 1811, she made such rapid progress under her mother's tuition that by Beethoven's advice she was placed under Czerny in her fifth year. She pursued composition as well as piano, and when twelve years old was able to appear in Vienna and play a set of variations with her own orchestral accompaniment. Among her later teachers were Moscheles, Kalkbrenner, and Sechter. She made frequent tours, and met with universal success. The criticisms of her work include an extremely favourable notice by Schumann. In 1840 she settled in Boulogne, where she became renowned as a teacher, and led a successful career until her death in 1887.
