Claudio Monteverdi, (baptized May 15, 1567, Cremona, Duchy of Milan [Italy]—died November 29, 1643, Venice),
Italian composer in the late Renaissance, the most important developer of the then new genre, the opera.

He also did much to bring a “modern” secular spirit into church music.

Early career

Monteverdi, the son of a barber-surgeon and chemist, studied with the director of music at Cremona cathedral,
Marcantonio Ingegneri, a well-known musician who wrote church music and madrigals of some distinction
in an up-to-date though not revolutionary style of the 1570s.

Monteverdi was obviously a precocious pupil, since he published several books of religious and secular music in his teens,
all of them containing competent pieces in a manner not far from that of his master.

The culmination of this early period occurred in two madrigal books published by one of the most famous
of Venetian printers in 1587 and 1590.

They are full of excellent, attractive works, somewhat more modern in approach than Ingegneri’s,
perhaps the result of studying the madrigals of Luca Marenzio, the greatest Italian madrigalist of the time, and others.

As yet, however, Monteverdi’s aim appeared to be to charm rather than to express passion;
it is exemplified at its best in such a madrigal as the well-known setting of the poem “Behold the Murmuring Sea” by Torquato Tasso.
