La Gioconda (opera)

La Gioconda is an opera in four acts by Amilcare Ponchielli set to an Italian libretto by Arrigo Boito (as Tobia Gorrio), based on Angelo, Tyrant of Padua, a 1835 play in prose by Victor Hugo (the same source Gaetano Rossi had used for his libretto for Mercadante's Il giuramento in 1837). First performed in 1876, La Gioconda was a major success for Ponchielli, as well as the most successful new Italian opera between Verdi's Aida (1871) and Otello (1887). It is also a famous example of the Italian genre of Grande opera, the equivalent of French Grand-Opéra. Ponchielli revised the work three times; the fourth and final version was first performed in 1879 in Genoa before reaching Milan in 1880 where its reputation as the definitive version was established.
