Task: Question Answering
Input (English): Passage: Claudio Giovanni Antonio Monteverdi (Italian: [ˈklaudjo monteˈverdi] (listen); 15 May 1567 (baptized) – 29 November 1643) was an Italian composer, string player and choirmaster. A composer of both secular and sacred music, and a pioneer in the development of opera, he is considered a crucial transitional figure between the Renaissance and the Baroque periods of music history.
Born in Cremona, where he undertook his first musical studies and compositions, Monteverdi developed his career first at the court of Mantua (c. 1590–1613) and then until his death in the Republic of Venice where he was maestro di capella at the basilica of San Marco. His surviving letters give insight into the life of a professional musician in Italy of the period, including problems of income, patronage and politics.
Much of Monteverdi's output, including many stage works, has been lost. His surviving music includes nine books of madrigals, large-scale sacred works such as his Vespro della Beata Vergine (Vespers) of 1610, and three complete operas. His opera L'Orfeo (1607) is the earliest of the genre still widely performed; towards the end of his life he wrote works for the commercial theatre in Venice, including Il ritorno d'Ulisse in patria and L'incoronazione di Poppea.
While he worked extensively in the tradition of earlier Renaissance polyphony, such as in his madrigals, he undertook great developments in form and melody, and began to employ the basso continuo technique, distinctive of the Baroque. No stranger to controversy, he defended his sometimes novel techniques as elements of a seconda pratica, contrasting with the more orthodox earlier style which he termed the prima pratica. Largely forgotten during the eighteenth and much of the nineteenth centuries, his works enjoyed a rediscovery around the beginning of the twentieth century. He is now established both as a significant influence in European musical history and as a composer whose works are regularly performed and recorded. 
Question: What is the last name of the person who is considered a crucial transitional figure between the Renaissance and the Baroque periods of music history?
Output (English): Monteverdi.
