 In this episode, we will discuss the music of the 15th century French composer Guillaume du Fayyé and how the lines that defined secular and sacred music began to blur in the late Middle Ages and early Renaissance. Guillaume du Fayyé was brought up as a choir boy in the Combré Cathedral in France. He learned his craft not from traditional academic study, but most likely from being a performer and serving as a music copyist for the older composers at the cathedral.
