Which opera had more people contribute to its writing and music, Don Giovanni or Béatrice et Bénédict?
Don Giovanni Don Giovanni (] ; K. 527; complete title: "Il dissoluto punito, ossia il Don Giovanni" , literally "The Rake Punished, namely Don Giovanni" or "The Libertine Punished") is an opera in two acts with music by Wolfgang Amadeus Mozart and Italian libretto by Lorenzo Da Ponte. It is based on the legends of Don Juan, a fictional libertine and seducer. It was premiered by the Prague Italian opera at the National Theater (of Bohemia), now called the Estates Theatre, on 29 October 1787. Da Ponte's libretto was billed as a "dramma giocoso", a common designation of its time that denotes a mixing of serious and comic action. Mozart entered the work into his catalogue as an "opera buffa". Although sometimes classified as comic, it blends comedy, melodrama and supernatural elements.
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.
