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 play in prose by Victor Hugo, dating from 1835. (This is the same source as Gaetano Rossi had used for his libretto for Mercadante's "Il giuramento" in 1837).
Opera Opera (] ; English plural: "operas"; Italian plural: "opere" ] ) is an art form in which singers and musicians perform a dramatic work combining text (libretto) and musical score, usually in a theatrical setting. In traditional opera, singers do two types of singing: recitative, a speech-inflected style and arias, a more melodic style, in which notes are sung in a sustained fashion. Opera incorporates many of the elements of spoken theatre, such as acting, scenery, and costumes and sometimes includes dance. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor.
