What was last opera?

There is no one single answer to the question of what was the last opera, as the term "opera" is applied to a wide variety of works and continues to be used by modern composers. However, some notable operas that were among the last composed within their respective traditions include:

- "Turandot" by Giacomo Puccini (1926) is considered the last "verismo" opera, known for its realistic portrayal of everyday life and human emotions.

- "L'Amour des trois oranges" by Sergei Prokofiev (1921) is one of the last major operas of the Russian Imperial era, combining avant-garde musical elements with a fantastic story.

- "The Rake's Progress" by Igor Stravinsky (1951) is often seen as the last of the modernist operas, known for its complex and dissonant music and allegorical story.

- "Nixon in China" by John Adams (1987) is considered a landmark of contemporary opera, addressing political themes and making use of minimalist musical techniques.

- "Dog Days" by David T. Little (2012) is a notable recent American opera, known for its exploration of personal and social issues and use of diverse musical influences.

These are just a few examples, and the concept of "last opera" remains subjective and dependent on various factors such as historical periods, musical styles, and cultural contexts.
