Italian composer. A singer at Milan cathedral from 1402-7 and between 1414 and 1416; in the intervening period he was at the archbishop of Milan's court at Pavia. His output consists of five Gloria settings, an isorhythmic motet and twenty-three chansons in various forms. Though an Italian he set French texts and embraced the most extreme and artificial manifestations of the virtuosic, rhythmically complex late fourtheenth century French school. His extravagantly dissonant and syncopated Le greygnour bienis one of the most extreme, even bizarre, pieces in this style, and is written out in such a way as to use the maximum number of subtle notational and mensural devices.
