Maurizio Cazzati was an Italian composer of the seventeenth century, born in Luzzara (Duchy of Mantua). Despite being almost unknown today, during his lifetime he served as a successful music director in many cities, including Mantua, Bozzolo, Ferrara and Bergamo. He was so well-thought-of that in 1657 he was invited to take the position of maestro di cappella of San Petronio Basilica in Bologna, without applying for it. Immediately after his appointment, he made some reforms that won him a general hostility from the musical community, and led to conflicts with other musicians. He was bitterly criticized by Lorenzo Perti (uncle of Giacomo Antonio Perti) and Giulio Cesare Arresti. Cazzati later declared that they were just jealous of his position. In 1671, he returned to Mantua, where he served the Duchess Isabella as Maestro di Cappella da Camera until his death. His instrumental music is nowadays considered the most important and influential part of his ouvre. His op. 35 contains the first known example of a trumpet sonata.
