The first music printer and publisher, active in Venice and Fossombrone in 1500-20. He used a multiple-impression method-first the words, then the staves, then the notes -a difficult process whose problems he overcame brilliantly to produce very elegant results. His earliest prints, the Odhecaton and two succeeding collections of secular music, were followed by luxurious volumes of Masses and motets, some devoted to individual composers ( Josquin , Obrecht , etc.), and books of frottolas, laude, lute music and keyboard pieces.
