Italian composer. He was maestro di cappellaat Genoa cathedral from c,1602, and issued a 6-volume edition of Gesualdo's madrigals, in score in 1613. His own canzonets, and church music for from one to ten voices, show the influence of Gesualdo in their declamatory style and advanced chromatic harmonies; the latter are also to be found in his 1599 lute book. This includes fantasias, and important examples of the variation suite consisting of groups of dances whose separate sections are all based on the same chord progression.
