Old Cambrai Cathedral in the context of Cambrai Cathedral

Guillaume Du Fay (/djuːˈfaɪ/ dyoo-FEYE, French: [ɡijom dy fa(j)i]; also Dufay, Du Fayt; 5 August 1397 – 27 November 1474) was a composer and music theorist of early Renaissance music, who is variously described as French or Franco-Flemish. Considered the leading European composer of his time, his music was widely performed and reproduced. Du Fay was well-associated with composers of the Burgundian School, particularly his colleague Gilles Binchois, but was never a regular member of the Burgundian chapel himself.

While he is among the best-documented composers of his time, Du Fay's birth and family is shrouded with uncertainty, though he was probably the illegitimate child of a priest. He was educated at Cambrai Cathedral, where his teachers included Nicolas Grenon and Richard Loqueville, among others. For the next decade, Du Fay worked throughout Europe: as a subdeacon in Cambrai, under Carlo I Malatesta in Rimini, for the House of Malatesta in Pesaro, and under Louis Aleman in Bologna, where he was ordained priest. As his fame began to spread, he settled in Rome in 1428 as musician of the prestigious papal choir, first under Pope Martin V and then Pope Eugene IV, where he wrote the motets Balsamus et munda cera, Ecclesie militantis and Supremum est mortalibus. Amid Rome's financial and political disorder in the 1430s, Du Fay took a leave of absence from the choir to serve Amadeus VIII, Duke of Savoy.

Josquin Lebloitte dit des Prez (c. 1450–1455 – 27 August 1521) was a composer of Renaissance music, who is variously described as French or Franco-Flemish. Considered one of the greatest composers of the Renaissance, he was a central figure of the Franco-Flemish School and had a profound influence on the music of 16th-century Europe. Building on the work of his predecessors Guillaume Du Fay and Johannes Ockeghem, he developed a complex style of expressive—and often imitative—movement between independent voices (polyphony) which informs much of his work. He further emphasized the relationship between text and music, and departed from the early Renaissance tendency towards lengthy melismatic lines on a single syllable, preferring to use shorter, repeated motifs between voices. Josquin was a singer, and his compositions are mainly vocal. They include masses, motets and secular chansons.

Josquin's biography has been continually revised by modern scholarship, and remains highly uncertain. Little is known of his early years; he was born in the French-speaking area of Flanders, and he may have been an altar boy and have been educated at the Cambrai Cathedral, or taught by Ockeghem. By 1477 he was in the choir of René of Anjou and then probably served under Louis XI of France. In the 1480s Josquin traveled Italy with the Cardinal Ascanio Sforza, may have worked in Vienna for the Hungarian king Matthias Corvinus, and wrote the motet Ave Maria ... Virgo serena, and the popular chansons Adieu mes amours and Que vous ma dame. He served Pope Innocent VIII and Pope Alexander VI in Rome, Louis XII in France, and Ercole I d'Este in Ferrara. Many of his works were printed and published by Ottaviano Petrucci in the early 16th century, including the Missa Hercules Dux Ferrariae. In his final years in Condé, Josquin produced some of his most admired works, including the masses Missa de Beata Virgine and Missa Pange lingua; the motets Benedicta es, Inviolata, Pater noster–Ave Maria and Praeter rerum seriem; and the chansons Mille regretz, Nimphes, nappés and Plus nulz regretz.

Richard Loqueville (died 1418) was a French composer active during the transition between Medieval and Renaissance music. A musician at Cambrai Cathedral, Loqueville was a harpist and teacher, whose students included Edward III, Duke of Bar and the influential composer Guillaume Du Fay.
