Mozart's ability to craft music closely suited to his singers took a remarkable turn with the soprano Adriana Ferrarese del Bene. This singer's career, from sporadic prominence in serious opera to notoriety as a prima donna in Viennese opera buffa in the late 1780s, was capped by her association with Mozart and Da Ponte in Così fan tutte (1790). Certain reports notwithstanding, Ferrarese seems to have been far from a great artist; her successes were modest and she never before or after attained the artistic triumph she achieved in the Mozart–Da Ponte opera. Reviews and contemporary comments suggest that her comic and dramatic skills were uneven, her vocal equipment impressive but incomplete and her performances less than inspiring. Mozart's achievement was to transform a particular set of vocal skills and limitations into something of exceptional artistic value; Fiordiligi was fashioned out of the temperament, vocal style and dramatic abilities – and limitations – of his soprano.

Il crociato in Egitto was the last in a series of Italian operas written by Giacomo Meyerbeer between 1817 and 1824. Although his Emma di Resburgo and Margherita d'Anjou had been successful in Venice and Milan, it was Il crociato that put Meyerbeer in the first rank of internationally renowned composers of Italian opera. The work's contemporary popularity makes it an important element in the history of early nineteenth-century Italian opera, and the abundant source material that survives for the opera permits a reconstruction of its early history. Furthermore, the publication in facsimile of a copyist's score from the première at La Fenice and the recording of the work by Opera Rara have encouraged a modern revaluation.

In little more than a year, between October 1892 and November 1893, the Italian operatic repertory acquired two ambitious and monumental works, similar in their choice of a national–historic subject and in their dramatic form: Alberto Franchetti's Cristoforo Colombo and Ruggero Leoncavallo's I Medici. After a few revivals scattered over several decades, both disappeared from circulation, and recent productions have confirmed doubts about their stageworthiness, notwithstanding some convincing passages (particularly in Colombo) and the enormous investment of intellectual and historical reflection that had attended their birth. Ideological motivations determined the musico-dramatic structures of the two operas, and are closely related to the failure of their projects.

In the early part of this century Italian musical critics were bemoaning the decadence of the national lyric stage. No inspired figure had come forth to claim the mande of Verdi; new Italian opera was becoming artistically irrelevant. In an effort to reclaim a ‘lyric spirit’ from Wagnerian Germany, Gabriele D'Annunzio ‘rediscovered’ the early seventeenth century as the birthplace of opera. Specifically, he fashioned Monteverdi – ‘il divino Claudio’ – as visionary proto-lyricist, a nostalgic move seconded by many other Italian authors through the 1920s and 30s.
