Sarti met Mozart in Vienna, en route for St. Petersburg. Mozart tipped his hat to Sarti by including a tune of his in ‘Don Giovanni’, and basing much of ‘The Marriage of Figaro’ on the Sarti opera the tune came from (da Ponte, who wrote Mozart’s libretto, may even have done the same for Sarti’s opera). Martini taught Sarti, and Cherubini was one of his pupils.
