 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.
Il burbero di buon cuore ("The Good-Hearted Curmudgeon") is an opera dramma giocoso in two acts by Vicente Martín y Soler.

 The opera premiered on January 4, 1786 in Vienna at the Burgtheater with a cast that included three well known Viennese singers of the day: Nancy Storace as Angelica, Francesco Benucci as Ferramondo, and Maria Mandini as Marina.
 The opera premiered in the same year and at the same house as Mozart's "Le nozze di Figaro", and both operas enjoyed revivals at the Burgtheater three years later — each boasting two new arias for new leading ladies.
 The new arias for "Il burbero di buon cuore" (""Chi sa, chi sa, qual sia"" K. 582 in Act I and ""Vado, ma dove?""
 K. 583 in Act II, both for Lucilla) were actually composed by Mozart, as Martín y Soler had left Vienna to work at the court of Catherine the Great in St. Petersburg.
 The opera recently received its first modern revival in 2007 at the Teatro Real in Madrid, a performance which was videotaped live and released on DVD in 2009.

 It received only three performances during the premiere, and the negative criticism it received in the press played a decisive role in Schumann's decision to not write a second opera.
