Don Giovanni is an opera in two acts with music by Wolfgang Amadeus Mozart and with Italian libretto by Lorenzo Da Ponte. It was premiered in the Estates Theatre in Prague on October 29, 1787. Of the many operas based on the legend of Don Juan, Don Giovanni is thought to be beyond comparison. Da Ponte's libretto was billed like many of its time as dramma giocoso: "giocoso" meaning comic, and "dramma" signifying an operatic text (an abbreviation of "dramma per musica"). Mozart entered the work into his catalogue as an "opera buffa". Although often classified as comic, it is a unique blend of comic (buffa) and drama (seria).
