The legacy of Pierre Attaingnant, Royal Printer of Music, has done much to clarify our knowledge of the French polyphonic chanson during the first half of the sixteenth century. The great Parisian printer's invention and introduction of music printing with movable type in 1528 contributed to an increasing coalescence in the style of the chansons composed in France between 1530 and 1550. By midcentury, composers at the French royal court and throughout the provinces, too, routinely composed what came to be known as Parisian chansons, the genre most clearly exemplified in the works of Claudin de Sermisy.
