Fiorello Giraud created a roll in an opera that had how many acts?
Pagliacci Pagliacci (] ; literal translation, "Clowns") is an Italian opera in a prologue and two acts, with music and libretto by Ruggero Leoncavallo. It is the only Leoncavallo opera that is still widely performed. Opera companies have frequently staged "Pagliacci" with "Cavalleria rusticana" by Mascagni, a double bill known colloquially as 'Cav and Pag'.
William Tell (opera) Guillaume Tell (English: William Tell , Italian: Guglielmo Tell ) is a French opera in four acts by Gioachino Rossini to a libretto by Étienne de Jouy and Hippolyte Bis. Based on Friedrich Schiller's play "William Tell," which drew on the William Tell legend, the opera was Rossini's last, although he lived for nearly forty more years. Fabio Luisi said that Rossini planned for "William Tell" to be his last opera even as he composed it. The overture, in four sections and featuring a depiction of a storm as well as a vivacious finale, the "March of the Swiss Soldiers," is often played.
