own work, but he also believed that it was an essentially American artform, much as opera was European. In 1946 he became a U.S. citizen, but he remained very close to Italy, which he frequently visited. In 1958 he won the Concorso Campari with the opera The Merchant of Venice, which was first performed in 1961 at the Maggio Musicale Fiorentino under the baton of Gianandrea Gavazzeni. In 1962 he wrote Les Guitares bien tempérées ("The Well-Tempered Guitars") for two guitars, a set of 24 preludes and fugues in all 24 major and minor keys, for the duo-guitarists Alexandre Lagoya and Ida Presti. This was inspired by The Well-Tempered Clavier by Johann Sebastian Bach, a composer Castelnuovo-Tedesco revered. In the United States, Castelnuovo-Tedesco also composed new operas and works based on American poetry, Jewish liturgy, and the Bible. He died in Beverly Hills, California, in 1968 at the age of 72. He is buried at Westwood Village Memorial Park Cemetery. The Library of Congress in Washington, DC, hosts the Mario Castelnuovo-Tedesco Collection, a collection of the composer's manuscripts donated by his family in 2000. The catalogue is accessible online. His son was the psychiatrist Pietro Castelnuovo-Tedesco. Works Castelnuovo-Tedesco's autobiography, A life in music: a book of memories, written shortly before his death, was published decades later: Una vita di musica: un libro di ricordi (in Italian), James Westby (ed.), with an introduction by Mila De Sanctis, Fiesole: Cadmo, 2005. Other writings by the composer have been catalogued. In 2018 a collection of contemporary guitar music in homage to Castelnuovo-Tedesco was published, edited by Piero Bonaguri. It includes works by composers Filippo Ferruggiara, Daniele Mandonico, Marco Reghezza, Marco Simoni, Alessandro Spazzoli, and Paolo Ugoletti. In 2018, a film was released about his life entitled The Maestro where he was portrayed by actor Xander Berkeley. The film was well received and won the Audience Award at the Tallgrass Film Festival the Jury Award at the Borrego Springs Film Festival in 2019, and the Youth Film Award at the Rhode Island International Film Festival in 2018. Xander Berkeley also received "Best Actor" awards at the 2017 Oaxaca Film Festival and the 2018 Albuquerque Film & Music Experience. References Sources and further reading Bardi, Aloma (2012).
