The document discusses the 14th century musical style known as Ars Nova and Guillame de Machaut, one of its most famous composers. The Ars Nova developed after periods of war and plague weakened the church's influence, allowing secular music to surpass sacred music. It featured new rhythmic patterns and notation. Machaut was a renowned composer and poet who served royalty, composing beautifully illustrated songs of courtly love. One of his works, Puis qu'en Oubli, contains eight lines in an ABAAABAB form for four voices. His Notre Dame Mass was the first known polyphonic setting of the mass ordinary.
