Another eighteenth century celebrity was Maddalena Sirmen, who won fame as one of the great Italian school of violinists. She was a pupil of the renowned Tartini, and held her own with the great performers of her time. Her works contain a number of violin concertos and a set of six trios for two violins and a 'cello, besides many smaller pieces. Most of these were wholly successful in performance. Maria Andreozzi, Marquise de Bottini, lived in the early part of the nineteenth century. Her works all show great merit, and cover a wide range in the matter of form. They include an opera, a requiem, a Stabat Mater, an orchestral Magnificat, the cantata "St. Cecile," another choral cantata, a number of concertos for piano, several overtures, and various compositions for voice, harp, and piano. It is only natural to find opera the most popular form for ambitious Italian composers to use in striving for public favour. Where each little town and village had its own opera-house, there was an opportunity for the public to become accustomed to this form, while other works stood less chance of production and brought less revenue to the composer. As early as 1764 we find the ballet music to the opera "Dario," published by Signora Bartalotti. In the next century, Ursula Asperi leads in point of time, her first opera having been given in 1827. She was conductor for a year at one of the Florentine theatres, and filled the post with admirable skill. Carolina Uccelli produced "Saul" in 1830, following it up with "Emma di Resburgo." Teresa Seneke obtained a Roman hearing for her opera, "Le Due Amichi," and published also a quantity of songs and piano music. Adolfa Galloni composed the opera, "Le Quattra Rustici," besides instrumental and vocal music. Signora Casella was another operatic composer, her "Cristoforo Colombo" having been produced at Nice in 1865. Teresa Guidi is the author of numerous operas of our own day, while the Countess Ida Correr, of Padua, has witnessed frequent performances of her "Gondoliera." Of the many women working in the smaller forms, Virginia Mariani has won prominence at present, not only by her songs and piano music, but by her cantata, "The Apotheosis of Rossini." Teresa Milanollo, a celebrated violinist of the past century, published a number of compositions for her instrument, besides various works for piano. Among other piano composers in Italy during the nineteenth century may be mentioned Teresa de Blasis, Natalie Bertini, Eugenia Appiani, Bertha Frugoni, Clary Zentner, and Adele Branca Mussini.
