The Marriage of Figaro (play)
The play formed the basis for an opera with a libretto by Lorenzo Da Ponte and music by Mozart, also called "The Marriage of Figaro" (1786). In 1799, another opera based on the same play, "La pazza giornata, ovvero Il matrimonio di Figaro", was produced in Venice with libretto by Gaetano Rossi and music by Marcos Portugal.
Writer
Libretti (the plural of libretto) are the texts for musical works such as operas. The Venetian poet and librettist Lorenzo Da Ponte, for example, wrote the libretto for some of Mozart's greatest operas. Luigi Illica and Giuseppe Giacosa were Italian librettists who wrote for Giacomo Puccini. Most opera composers collaborate with a librettist but unusually, Richard Wagner wrote both the music and the libretti for his works himself.
