Don Giovanni is a dramatic comedy in two acts composed by Wolfgang Amadeus Mozart with a libretto by Lorenzo Da Ponte. It premiered in Prague in 1787. The opera is generally regarded as one of the greatest works in all of opera.
Leporello, servant to Don Giovanni, keeps watch outside the Commendatore’s home at dawn. The Commendatore’s daughter, Anna, rushes out, struggling with the masked Giovanni, who has sneaked into her bedroom and ravaged her. The angry Commendatore challenges Giovanni to a duel and is killed. The traumatized Anna tells her fiancé́, Ottavio to swear that he will avenge her father’s death.
Looking for his next conquest, Giovanni encounters Elvira, who he vowed to marry and abandoned. Leporello shows her his little black book with the names of every woman his master has seduced – more than 1,000 in Spain alone.
Peasants celebrate the marriage of Masetto and Zerlina, who has caught the Don’s eye. He uses his status as a nobleman to entice the young girl, promising to marry her. His attempt at seduction is stopped by Elvira, who urges Zerlina to ignore his advances. She also warns Anna, who is still unaware that Giovanni killed her father. As he leaves, Anna recognizes the voice of the man who killed her father. Shaken at the thought of a nobleman being a rapist and murdere, she is determined to avenge her father and her honor. Giovanni, who has invited Zerlina and Masetto to his villa for the wedding party, prepares for an evening of drinking and dancing – his real objective is to seduce Zerlina.
Anna, Elivira and Ottavio also arrive at the wedding feast, but masked to conceal their identities. In the ballroom, Giovanni dances with Zerlina, then tries to drag her into the adjoining room. When she cries for help, Giovanni accuses Leporello of being the aggressor. Anna, Elvira, and Ottavio remove their masks and with Zerlina and Masetto, accuse Giovanni, who manages to escape.
