List of prominent operas

Since the origins of opera in late 16th century Italy, a central repertoire has developed, shepherded by major opera composers. The earliest major opera composer is generally considered to be Claudio Monteverdi,^[1] who wrote the first prominent opera, L'Orfeo, followed by two others. Throughout the later 17th century, his successor Francesco Cavalli and the Englishman Henry Purcell wrote numerous prominent operas. The early 18th century was dominated by the operas of George Frideric Handel, while other important works include Pepusch's The Beggar's Opera, Pergolesi's' La serva padrona, and various works by Jean-Philippe Rameau.

This list provides a guide to the most prominent operas, as determined by their presence on a majority of selected compiled lists, which date from between 1984 and 2000. The operas included cover all important genres, and include all operas regularly performed today, from seventeenth-century works to late twentieth-century operas. The brief accompanying notes offer an explanation as to why each opera has been considered important. The organisation of the list is by year of first performance, or, if this was long after the composer's death, approximate date of composition.

• 1607 L'Orfeo (Claudio Monteverdi). Widely regarded as the first operatic masterwork.^[2]
• 1640 Il ritorno d'Ulisse in patria (Monteverdi). Monteverdi's first opera for Venice, based on Homer's Odyssey, displays the composer's mastery of portrayal of genuine individuals as opposed to stereotypes.^[3]
• 1642 L'incoronazione di Poppea (Monteverdi). Monteverdi's last opera, composed for a Venetian audience, is often performed today. Its Venetian context helps to explain the complete absence of the moralizing tone often associated with opera of this time.^[4]
• 1644 Ormindo (Francesco Cavalli). One of the first of Cavalli's operas to be revived in the 20th century, Ormindo is considered one of his more attractive works.^[5]

• 1740 Alfred (Thomas Arne). An English opera of all times, famous for the patriotic song "Rule Britannia".

• 1950 The Consul (Menotti). This opera contains some of Menotti's most dissonant music.^[215]
