Claudio Giovanni Antonio Monteverdi (1567 - 1643) was an Italian composer, gambist, singer and Roman Catholic priest. Monteverdi's work, often regarded as revolutionary, marked the change from the Renaissance style of music to that of the Baroque period. He developed two styles of composition the heritage of Renaissance polyphony and the new basso continuo technique of the Baroque. Monteverdi wrote one of the earliest operas, L'Orfeo, a novel work that is the earliest surviving opera still regularly performed. He is widely recognized as an inventive composer who enjoyed considerable fame in his lifetime. 'Non si levav'ancor' is the first madrigal of the second book of madrigals for 5 voices, published in 1590.
