his works

Dufay was one of the most highly regarded composers of his generation, having composed such landmark works as Adieu ces bons vins de Lannoys and Apostolo gloriosopart, two compositions for which a specific historical occasion can be identified. His music flows more smoothly than the characteristically complex textures of the Medieval period, and is marked by graceful melodies and a compelling sense of direction. Dufay's early songs already show this style with full mastery, illustrating his most facile & exuberant command of melody and counterpoint.His four masses "L'homme arme," "Se la face ay pale,""Ecce ancilla domini," and "Ave regina caelorum" are what was to become the dominant style of mass composition. The Missa "Se la face ay pale" is probably the earliest surviving mass based on a secular theme, previous cantus-firmus masses having been based on liturgical chant.. These cantus firmus masses in four parts are his most famous works today, and were apparently instrumental in solidifying the position of this genre as central to the development of fifteenth century music
