Rossini tested the humble thirteen-year-old girl himself, had her admitted to the school with special treatment, and even procured her an early engagement to tour his Stabat Mater around Northern Italy, so that she could pay for her studies.
[3] After she achieved her diploma and made a modest debut in Bologna, in 1842, as "Climene" in Pacini's Saffo, she obtained a triennial engagement thanks to Rossini's influence on the impresario Bartolomeo Merelli, Intendant at both Milan's Teatro alla Scala and Vienna's Imperial Kärntnertortheater.
In the season 1844–1845 she was engaged in the Saint Petersburg Imperial Bolshoi Kamenny Theatre; later, in 1846–47, she toured the principal cities of Central Europe, finally reaching London and Paris, where she settled permanently.
[10] There she sang, alongside Adelina Patti, the leading soprano of the time, a stanza of Dies irae, "Liber scriptum", adjusted to the music of the duet "Quis est Homo" from Rossini's own Stabat Mater.
[11] In 1872 she permanently retired from the stage with four performances of "Fidalma" in Cimarosa's Il matrimonio segreto, at the Paris Théâtre des Italiens[12] but, in fact, she never gave up singing in private and in benefit concerts.
[15] Alboni's voice, an exceptionally fine contralto with a seamless compass of two and one-half octaves, extending as high as the soprano range,[17] was said to possess at once power, sweetness, fullness, and extraordinary flexibility.
She possessed vivacity, grace, and charm as an actress of the comédienne type; but she was not a natural tragédienne, and her attempt at the strongly dramatic part of Norma was sometimes reported to have turned out a failure.
[18] Nevertheless, she scored a real triumph in 1850, when she made her operatic debut at the Paris Opéra performing the tragic role of "Fidès" in Meyerbeer's Le prophète, which had been created the year before by no less than Pauline Viardot.
