Francesco Maria Piave in the context of "La traviata"

Macbeth (Italian pronunciation: [ˈmakbet], also [makˈbɛt]) is an opera in four acts by Giuseppe Verdi, with an Italian libretto by Francesco Maria Piave and additions by Andrea Maffei, based on William Shakespeare's play of the same name. Written for the Teatro della Pergola in Florence, Macbeth was Verdi's tenth opera and premiered on 14 March 1847. It was the first Shakespeare play that Verdi adapted for the operatic stage. Almost twenty years later, Macbeth was revised and expanded into a French version and given in Paris on 21 April 1865.

After the success of Attila in 1846, by which time the composer had become well established, Macbeth came before the great successes of 1851 to 1853 (Rigoletto, Il trovatore and La traviata) which propelled him into universal fame. As sources, Shakespeare's plays provided Verdi with lifelong inspiration: some, such as an adaption of King Lear (as Re Lear) were never realized, but he wrote his two final operas using Othello as the basis for Otello (1887) and The Merry Wives of Windsor as the basis for Falstaff (1893).

Rigoletto is an opera in three acts by Giuseppe Verdi. The Italian libretto was written by Francesco Maria Piave based on the 1832 play Le roi s'amuse by Victor Hugo. Despite serious initial problems with the Austrian censors who had control over northern Italian theatres at the time, the opera had a triumphant premiere at La Fenice in Venice on 11 March 1851.

Simon Boccanegra (Italian: [siˈmom ˌbokkaˈneːɡra]) is an opera with a prologue and three acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the play Simón Bocanegra (1843) by Antonio García Gutiérrez, whose play El trovador had been the basis for Verdi's 1853 opera, Il trovatore.

Simon Boccanegra was first performed at Teatro La Fenice in Venice on 12 March 1857. Given the complications of the original plot and the generally poor popular response – although the critical one was more encouraging – the opera dropped out of favour after 1866. Finally, 23 years later, Verdi's publisher persuaded the composer to revise the opera, with text changes to be prepared by Arrigo Boito, the librettist who aspired to work with the aging composer on a project which eventually became a new opera, Otello, but to whom Verdi had not totally committed at that time.

Ernani is an operatic dramma lirico in four acts by Giuseppe Verdi to an Italian libretto by Francesco Maria Piave, based on the 1830 play Hernani by Victor Hugo.

Verdi was commissioned by the Teatro La Fenice in Venice to write an opera, but finding the right subject took some time, and the composer worked with the inexperienced Piave in shaping first one and then another drama by Hugo into an acceptable libretto. As musicologist Roger Parker notes, the composer "intervened on several important points, insisting for example that the role of Ernani be sung by a tenor (rather than by a contralto as had originally been planned)".
