What was the first opera to be created in the world?

The art form known as opera originated in Italy in the sixteenth and seventeenth centuries.The word opera, meaning "work" in Italian, was first used in the modern musical and theatrical sense in 1639 and soon spread to the other European languages. The earliest operas were modest productions compared to other Renaissance forms of sung drama, but they soon became more lavish and took on the spectacular stagings of the earlier genre known as "intermedio".

"Dafne" by Jacopo Peri was the earliest composition considered opera, as understood today, although with only five instrumental parts it was much more like a chamber opera than either the preceding intermedi or the operas of Claudio Monteverdi a few years later. It was written around 1597, largely under the inspiration of an elite circle of literate Florentine humanists who gathered as the "Camerata". Significantly, "Dafne" was an attempt to revive the classical Greek drama, part of the wider revival of antiquity characteristic of the Renaissance. The members of the Camerata considered that the "chorus" parts of Greek dramas were originally sung, and possibly even the entire text of all roles; opera was thus conceived as a way of "restoring" this situation. Most of the music for "Dafne" is lost (the libretto was printed and survives), but one of Peri's many later operas, "Euridice", dating from 1600, is the first opera score to have survived to the present day.
