La scuola de' gelosi (The School of Jealousy) is a dramma giocoso in two acts by Antonio Salieri, set to a libretto by Caterino Mazzolà.
It was first performed at the Teatro San Moisè in Venice on 27 December 1778. In 1783 it was given in Vienna, to inaugurate the reestablishment of the Italian Opera troupe. Salieri revised the score for the 1783 performances, creating new arias and expanding the role of woodwinds and brass in the scoring of the work. The cast including Francesco Benucci as Blasio and Nancy Storace as the countess, the original Figaro and Susanna in Mozart's The Marriage of Figaro. It reached London in 1786, where, as in many other European cities, it enjoyed great success. Franz Joseph Haydn composed two insertion arias for the work, one lost, the surviving aria, Dice benissimo, for bass & orchestra, H. 24b/5.
The plot of the opera involves love intrigues, attempted seductions and provocations to jealousy between members of the three different social strata: the aristocracy, the bourgeoisie and the working class. The role of the Lieutenant is a close parallel to that of Don Alfonso in Mozart's Così fan tutte.
