Lorenzo Da Ponte
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.
