Please answer the following question: What is the answer for the question: Which works require three voices including a narrator? from the following article ?  (English: "Armida abandoned") After the rejection of Licori, Monteverdi did not immediately turn his attention to Armida. Instead, he went to Parma, having been commissioned to provide musical entertainments for the marriage celebrations of the youthful Duke Odoardo Farnese of Parma and Margherita de' Medici. He spent several weeks in Parma working on these; nevertheless, on 18 December 1627 he was able to tell Striggio that the music for Armida had been completed and was being copied. In the relevant section of Tasso's poem, the enchantress Armida lures the noble Rinaldo to her enchanted island. Two knights arrive to persuade Rinaldo to return to his duty, while Armida pleads with him to stay, or if he must depart, to allow her to be at his side in battle. When he refuses and abandons her, Armida curses him before falling insensible.Carter indicates several structural similarities to Il combattimento; both works require three voices, one of which acts as the narrator. Despite these similarities, Armida abbandonata, unlike the earlier work, is generally considered by scholars of Monteverdi to be an opera, although Denis Stevens, translator of Monteverdi's letters, has termed it a "parergon" (subsidiary work) to Il Combattimento.Plans for Armida's performance were, however, cancelled when Duke Vincenzo died at the end of December 1627. On 4 February 1628, Striggio was still asking for a copy of Armida, perhaps to use in connection with the next duke's coronation. Monteverdi promised to send him one, but there is no confirmation that he did so. No trace of the music has been found, though Tomlinson has deduced some of its likely characteristics from Monteverdi's correspondence, including extensive use of the stile concitato effect. Although there is no record that Armida was ever performed in Mantua, Stevens has mooted the possibility that it may have been staged in Venice in 1628, since Monteverdi's reply to Striggio's February letter indicates that the work was in the hands of Girolamo Mocenigo, a wealthy...
