Claudio Monteverdi was an Italian composer, gambist, singer and Roman Catholic priest.[2] Monteverdi’s work, often regarded as revolutionary, marked the change from the Renaissance style of music to that of the Baroque period.[3] He developed two styles of composition – the heritage of Renaissance polyphony and the new basso continuo technique of the Baroque.[4] Monteverdi wrote one of the earliest operas, L’Orfeo, a novel work that is the earliest surviving opera still regularly performed.
