wrote several works for the stage between 1604 and 1643, including ten works of the then-emerging opera genre. For three of these, the music and libretto are extant: L'Orfeo, Il ritorno d'Ulisse in patria, and L'incoronazione di Poppea. Seven other opera projects are known, of which four were completed and performed during Monteverdi's lifetime, while he abandoned the other three at some point. The libretto has survived for some of these lost operas. The opera genre emerged during Monteverdi's earlier career, first as courtly entertainment trying to revive Greek theatre. The first known work to be regarded as an opera in the modern sense is Dafne by Jacopo Peri, and his Euridice is the earliest surviving one. Since Monteverdi served as the court composer for the Gonzaga family from 1590 to 1612, he likely joined Duke Vincenzo Gonzaga in Florence for the 6 October 1600 premiere of Euridice. While Monteverdi's own impressions of the work are unknown, the duke realised the potential of this new art form and sought to gain prestige from the patronage of it. Therefore, he commissioned Monteverdi in late 1606 for a work which is now considered as the "birth of Western Opera", L'Orfeo, on a libretto by Alessandro Striggio the Younger. In 1613 Monteverdi became maestro di cappella at St Mark's Basilica in Venice, where he continued to compose operas for the Gonzaga court and later for the publicTeatro Santi Giovanni e Paolo in Venice. The only two that survive are Il ritorno d'Ulisse in patria on a libretto by Giacomo Badoaro and his final opera, L'incoronazione di Poppea, on a book by Giovanni Francesco Busenello. Seven of his operas are lost. Of these, L'Arianna, Andromeda, Proserpina rapita and Le nozze d'Enea con Lavinia were completed and performed during Monteverdi's lifetime. The other three lost operas, Le nozze di Tetide, La finta pazza Licori and Armida abbandonata, were never finished, so it is unknown how much music was completed, if any. For some of them, at least the libretto survived, by authors including Scipione Agnelli, Ercole Marigliani, Ottavio Rinuccini, Giulio Strozzi and Torquato Tasso. The term opera was not widely used until the late 17th century, so Monteverdi's musical stage works were known by various names such as favola in musica, dramma in musica, or tragedia in musica. Monteverdi was instrumental in developing and popularizing the genre for public musical theatre, his L'Orfeo is the earliest opera still regularly performed.

Operas
''L'Orfeo''
Monteverdi composed L'Orfeo, a favola in musica, to a libretto by Alessandro Striggio for the annual carnival season in Mantua in 1607. Commissioned by the, it was premiered at the Ducal Palace on 4 February 1607. The work is the earliest opera still frequently performed and recorded. The libretto is written with dramatic instinct, different from earlier experiments in the new genre.
''L'Arianna''
L'Arianna, a tragedia in musica, was written for the wedding celebrations of Duke Vincenzo's oldest son and heir Francesco and Margaret of Savoy. The libretto by Rinuccini is based on the Greek Ariadne myth. It was premiered at the Ducal Palace on 28 May 1608.
''Le nozze di Tetide''
Le nozze di Tetide, a favola marittima, was a project for the wedding celebrations of Duke Ferdinando and Catherine de' Medici. Monteverdi was given the libretto by Scipione Agnelli without an author's name, which he criticised in a letter dated 9 December 1616. He began composing, but the commission was cancelled in January 1617.
''Andromeda''
Andromeda, a favola in musica, was commissioned by Don Vincenzo Gonzaga for the Mantua Carnival of March 1618, to a libretto by Marigliani. Due to Monteverdi's disinterest it took two years to complete and premiered during the 1620 Carnival season, 1–3 March. The music is lost, but the libretto, long believed to be lost as well, was rediscovered in 1984.
''Armida abbandonata''
Armida abbandonata was written to a libretto by Torquato Tasso, intended for the wedding celebrations of Duke Odoardo of Parma and Margherita de' Medici. While Monteverdi completed the music, the performance was canceled due to the duke's death at the end of December 1627. Only a song for three voices, "Come dolce oggi l'auretta", survived.
''La finta pazza Licori''
La finta pazza Licori was commissioned by the Mantua court secretary, Alessandro Striggio the Younger, probably to celebrate the ascension of Duke Vincenzo II. The work is the first known attempt at a comic opera, but Striggio did not like Strozzi's libretto and cancelled the commission in September 1627.
''Proserpina rapita''
Proserpina rapita, an anatopismo, was composed to a libretto by Strozzi for the wedding celebrations of Lorenzo Giustiniani and Giustiniana Mocenigo, and premiered at the Mocenigo Palace in Venice on 16 April 1630. Only a song for three voices, "Come dolce oggi l'auretta", survived.
''Il ritorno d'Ulisse in patria''
After the first public theatre opened in Venice, the Teatro San Cassiano in 1637, Monteverdi composed a trilogy of operas for public theatre in Venice, beginning with Il ritorno d'Ulisse in patria, a dramma per musica, to a libretto by Badoaro. It was premiered at the Teatro Santi Giovanni e Paolo during the 1639–40 carnival season.
''Le nozze d'Enea con Lavinia''
Le nozze d'Enea con Lavinia, a tragedia di lieto fine, with another libretto by Badoaro, was the second opera written for the Teatro Santi Giovanni e Paolo and first performed in the 1640–41 carnival season. While the libretto survives, the music is lost.
''L'incoronazione di Poppea''
L'incoronazione di Poppea, a dramma musicale, to a libretto by Busenello was the final opera of the trilogy for the Teatro Santi Giovanni e Paolo, where it was first performed during the 1643 carnival season. It was one of the first operas based on historical events and people.
