Guillaume Du Fay, French composer and music theorist (born 1397)

Guillaume Du Fay 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.
