<P> John Dunstaple (or Dunstable) (ca . 1390--1453) was an English composer of polyphonic music of the late medieval era and early Renaissance periods . He was one of the most famous composers active in the early 15th century, a near - contemporary of Power, and was widely influential, not only in England but on the continent, especially in the developing style of the Burgundian School . Dunstaple's influence on the continent's musical vocabulary was enormous, particularly considering the relative paucity of his (attributable) works . He was recognized for possessing something never heard before in music of the Burgundian School: la contenance angloise ("the English countenance"), a term used by the poet Martin le Franc in his Le Champion des Dames . Le Franc added that the style influenced Dufay and Binchois . Writing a few decades later in about 1476, the Flemish composer and music theorist Tinctoris reaffirmed the powerful influence Dunstaple had, stressing the "new art" that Dunstaple had inspired . Tinctoris hailed Dunstaple as the fons et origo of the style, its "wellspring and origin ." </P> <P> The contenance angloise, while not defined by Martin le Franc, was probably a reference to Dunstaple's stylistic trait of using full triadic harmony (three note chords), along with a liking for the interval of the third . Assuming that he had been on the continent with the Duke of Bedford, Dunstaple would have been introduced to French fauxbourdon; borrowing some of the sonorities, he created elegant harmonies in his own music using thirds and sixths (an example of a third interval is the notes C and E; an example of a sixth interval is the notes C and A). Taken together, these are seen as defining characteristics of early Renaissance music . Many of these traits may have originated in England, taking root in the Burgundian School around the middle of the century . </P> <P> Because numerous copies of Dunstaple's works have been found in Italian and German manuscripts, his fame across Europe must have been widespread . Of the works attributed to him only about fifty survive, among which are two complete masses, three connected mass sections, fourteen individual mass sections, twelve complete isorhythmic motets and seven settings of Marian antiphons, such as Alma redemptoris Mater and Salve Regina, Mater misericordiae . Dunstaple was one of the first to compose masses using a single melody as cantus firmus . A good example of this technique is his Missa Rex seculorum . He is believed to have written secular (non-religious) music, but no songs in the vernacular can be attributed to him with any degree of certainty . </P> <P> Oswald von Wolkenstein (ca . 1376--1445) is one of the most important composers of the early German Renaissance . He is best known for his well - written melodies, and for his use of three themes: travel, God and sex . </P>
