Claudio Monteverdi

Italian composer (mainly madrigals and operas), gambist, and singer (born in Cremona, 15 May 1567 (baptized) – died in Venice, 29 November 1643).
Monteverdi's work is often regarded as revolutionary and marked the transition from the Renaissance style to that of the Baroque period. He developed two individual styles of composition: the new basso continuo technique of the Baroque and the heritage of Renaissance polyphony. Enjoying fame in his lifetime, he wrote one of the earliest operas, L'Orfeo, which is still regularly performed.
