I Capuleti e i Montecchi (The Capulets and the Montagues) is an Italian opera (Tragedia lirica) in two acts by Vincenzo Bellini. The libretto by Felice Romani was a reworking of the story of Romeo and Juliet for an opera by Nicola Vaccai called Giulietta e Romeo and based on the play of the same name by Luigi Scevola written in 1818, thus an Italian source rather than taken directly from William Shakespeare. Bellini was persuaded to write the opera for the 1830 Carnival season at the Teatro La Fenice in Venice, with only a month and a half available for composition. He succeeded by appropriating a large amount of music previously written for his unsuccessful opera Zaira. The first performance of I Capuleti e i Montecchi took place on 11 March 1830. Composition history After Zaira Following the poor reception which Zaira received in Parma, Bellini returned to Milan by the end of June 1829 with no contract for another opera in sight. Giovanni Pacini, another Catanese composer, was still in Milan after the well-received premiere of his Il Talismano, and he received offers to compose an opera for both Turin and Venice for the following Carnival season. He accepted both offers, but the La Fenice impresario, Alessandro Lanari, included a proviso that if he were to be unable to fulfill the Venice contract, then it would be transferred to Bellini. A firm offer of a contract for a new opera for Venice appeared in the autumn, a contract which also included a provision that Il pirata would also be given during the 1830 Carnival season. By mid-December Bellini was in Venice where he heard the same singers who were to perform in Pirata: they were Giuditta Grisi, the tenor Lorenzo Bonfigli, and Giulio Pellegrini. Bellini in Venice With rehearsals for Pirata underway in late December, Bellini was given notice by Lanari that it was doubtful whether Pacini would be present in time to stage an opera and that a contract was to be prepared for Bellini to provide a new opera but with the proviso that it would only become effective on 14 January. Accepting the offer on 5 January, Bellini stated that he would set Romani's libretto for Giulietta Capellio, that he required 45 days between receipt of the libretto and the first performance, and that he would accept 325 napoleoni d'oro (about 8,000 lire).
