He may have studied with his uncle Giacinto Bondioli. His works were printed and influential throughout the European musical world. He traveled throughout his life, and occupied posts in Brussels, over thirty years in Neuburg an der Donau and Düsseldorf, and Venice in 1615, joining Monteverdi's group at St. Mark's Cathedral, Padua, Parma, Ferrara, Milan, Bergamo, and Brescia in Italy.
