An important transitional figure of the 17th century was Claudio Monteverdi. Who was an Italian string player, composer and choirmaster born on May 5th, 1567 in Cremona, Italy. It is said that he composed his first book of madrigals by the age of 17 and became a musician in the court of Mantova at 24, where he eventually became the music leader. By his mid-40s, he would be seen as the most celebrated composer in Italy. Meanwhile, around the year 1600, a group of Florentine intellectuals introduced their fledgling concept of opera, an imitation of ancient Greek drama. In 1607, Monteverdi took this rudimentary approach and turned it on its head with, arguably, the first true opera, “L’Orfeo.” He wrote both secular and sacred music, was a pioneer in the development of opera and was one of the masters of the madrigal. His revolutionary debut defied all existing musical convention. His work, considered ground-breaking, manifested the revolution from the Renaissance form of music thereto of the Baroque period.
