Giovanni Gabrieli is an important transitional figure between the Renaissance and Baroque eras and their associated musical styles. The distinctive sound of his music derived in part from his association with St. Mark's Cathedral in Venice, long one of the most important churches in Europe, and one for which he wrote both vocal and instrumental works. Through his compositions and his work with several significant pupils, Gabrieli substantially influenced the development of music in the 16th century.

Very little is known about his early years; he probably studied with his famous uncle Andrea Gabrieli, who was also a composer, and an organist at St. Mark's. Like his uncle, Gabrieli lived in Germany for several years, and was employed at the court of Duke Albrecht V in Munich from around 1575 until the Duke's death in 1579. Soon afterward, Gabrieli returned to Italy, and in 1585 became the organist for the Scuola Grande di San Rocco, a religious confraternity; he would hold that post for the rest of his life. That same year (1585), Gabrieli became organist at St. Mark's and, on his uncle's death in 1586, assumed his position as its principal composer (Gabrieli also edited a number of his uncle's compositions for posthumous publication).

At that time, Venice was a very cosmopolitan city and something of a musical crossroads. Much of the city's musical activity centered around St. Mark's Cathedral, which had long attracted many great musicians. The Cathedral's unusual layout, with its two choir lofts facing each other (each with its own organ), led to the development of what has been called the Venetian style of composition -- a colorful and dramatic style often involving multiple choirs and instrumental ensembles; many of Gabrieli's motets and other religious choral works are written for two or four choirs, divided into a dozen or more separate parts. Gabrieli also became one of the first composers to write choral works including parts for instrumental ensembles; the motet In ecclesiis, as an example, calls for two choirs, soloists, organ, brass, and strings. Gabrieli wrote a number of secular vocal works (most or all of them before 1600), and a number of pieces for organ in a quasi-improvisational style.

Gabrieli composed many purely instrumental works in forms such as the canzoni and ricercari, which had become increasingly popular in the 16th century. Several of these were published with some of his choral music in the collection Sacrae symphoniae (1597). This publication was very popular all over Europe and attracted a number of prominent pupils to Gabrieli, the best known of whom were Heinrich Schütz (who studied with him between 1609 and 1612) and Michael Praetorius. More of Gabrieli's instrumental pieces were published posthumously in Canzoni e sonate (1615). Some of these works were particularly innovative: the Sonata pian e forte was one of the first documented compositions to employ dynamic markings, and the Sonata per tre violini was one of the first to use a basso continuo, anticipating the later trio sonata. His instrumental works are now seen as the culmination of the development of instrumental music in the 16th century.

From around 1606, Gabrieli suffered from kidney stones that reduced his activities and eventually led to his death. ~ Chris Morrison, Rovi
