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.

K. 583 in act 2, both for Lucilla[3]) were actually composed by Mozart, as Martín y Soler had left Vienna to work at the court of Catherine the Great in Saint Petersburg.

The opera received its first modern revival in 2007 at the Teatro Real in Madrid directed by Irina Brook, with Elena de la Merced (Angelica), Véronique Gens (Lucilla), Cecilia Díaz (Marina), Saimir Pirgu (Giocondo), Juan Francisco Gatell (Valerio), Carlos Chausson (Ferramondo), and Luca Pisaroni (Dorval) conducted by Christophe Rousset,[4] a performance of which was videotaped live and released on DVD in 2009.
