and one of the three most famous composers of the early 15th century. While often ranked behind his contemporaries Guillaume Dufay and John Dunstaple by contemporary scholars, his works were still cited, borrowed and used as source material after his death. Binchois is considered to be a fine melodist, writing carefully shaped lines which are easy to sing and memorable. His tunes appeared in copies decades after his death and were often used as sources for mass composition by later composers. Most of his music, even his sacred music, is simple and clear in outline, sometimes even ascetic (monk-like). A greater contrast between Binchois and the extreme complexity of the ars subtilior of the prior (fourteenth) century would be hard to imagine. Most of his secular songs are rondeaux, which became the most common song form during the century. He rarely wrote in strophic form, and his melodies are generally independent of the rhyme scheme of the verses they are set to. Binchois wrote music for the court, secular songs of love and chivalry that met the expectations and satisfied the taste of the Dukes of Burgundy who employed him, and evidently loved his music accordingly. About half of his extant secular music is found in the Oxford Bodleian Library. Guillaume Du Fay (c. 1397–1474) was a Franco-Flemish composer of the early Renaissance. The central figure in the Burgundian School, he was regarded by his contemporaries as the leading composer in Europe in the mid-15th century. Du Fay composed in most of the common forms of the day, including masses, motets, Magnificats, hymns, simple chant settings in fauxbourdon, and antiphons within the area of sacred music, and rondeaux, ballades, virelais and a few other chanson types within the realm of secular music. None of his surviving music is specifically instrumental, although instruments were certainly used for some of his secular music, especially for the lower parts; all of his sacred music is vocal. Instruments may have been used to reinforce the voices in actual performance for almost any of his works. Seven complete masses, 28 individual mass movements, 15 settings of chant used in mass propers, three Magnificats, two Benedicamus Domino settings, 15 antiphon settings (six of them Marian antiphons), 27 hymns, 22 motets (13 of these isorhythmic in the more angular, austere 14th-century style which gave way to more melodic, sensuous treble-dominated part-writing with phrases ending in the "under-third"
