For this season, I decided to see only three operas at the Met. Mozart’s Cosi fan Tutte is the second opera for me this year. Cosi fan tutte is opera buffa which means, in short, that nobody dies! That was one of my criteria for building a short series of three operas this year. As I’ve said before, I’m not exactly an opera aficionado, but I did find the duet and ensemble singing in this opera to be some of the finest I’ve heard. The production starred Guanqun Yu and Isabel Leonard as the sisters Fiordiligi and Dorabella, Matthew Polenzani and Rodion Pogossov are their lovers, and Danielle de Niese as the scheming Despina. James Levine returned to the Met as music director.
