Between 1553 and 1558 he published four lute collections in cooperation with Michel Fezandat and six lute collections compiled by Albert de Rippe. During 1552–53 he also published three books of his own compositions for four-course Renaissance guitar, including fantasies and dances. He additionally published lute arrangements of works by Pierre Certon and Claudin de Sermisy.
