The Coro del Teatro alla Scala is synonymous with prestige and artistic quality. Notable previous chorus masters include Vittore Veneziani, Norberto Mola, Roberto Benaglio, and Romano Gandolfi who worked alongside Claudio Abbado, Giulio Bertola, and Roberto Gabbiani who worked with Riccardo Muti. Current chorus master Bruno Casoni has developed a powerful and moving sound.

Although the Chorus’s main focus is opera, it also performs a wide variety of repertoire, including choral symphonies, chamber music and contemporary 20th-century pieces. Notable works include Mottetti and Tres sacrae cantiones by Gesualdo, Luca Marenzio’s Missa Super iniquos odio habui, Missa L’homme armé by Carissimi and Verdi’s Requiem. The Chorus, alongside the other companies of the Teatro alla Scala, has participated in numerous European and world tours, and has visited Russia, the United States, Canada, Japan and Korea.
