Joseph Haydn is not primarily remembered as a composer of opera, yet the genre occupied a great deal of his time. During the 1770s and 1780s, Haydn ran an opera troupe on behalf of his employer, Prince Nikolaus Esterházy, which put on up to 150 performances per year. A number of the operas were Haydn's own work. Haydn's operas are only occasionally performed today.
The list is arranged chronologically and divided by career stage.
Composed as a freelance musician
1752: Der krumme Teufel, Hob. 29/1a, Singspiel (libretto by Joseph von Kurz), composed during Haydn's time as a freelance musician. Now lost.
Composed during Haydn's service for the Eszterházy family
Composed for the first London journey
1791: L'anima del filosofo, Hob. 28/13, dramma per musica in 4 acts (libretto by Carlo Francesco Badini). Haydn's own version of the Orpheus tale, the plot of a great many operas. Haydn's only post-Esterházy opera, composed for his 1791 trip to London but never performed there, due to intrigues.
