The Contenance angloise, or English manner, a distinctive style of musical polyphony, developed in fifteenth-century England. It uses full, rich harmonies based on the third and sixth. It became highly influential in the fashionable Burgundian court of Philip the Good (r. 1419–1467), and on European music of the era. Its leading proponent was John Dunstaple (c. 1390 - 1453), followed by Walter Frye and John Hothby (c. 1410 - 1487).
