Ay me! dame de valour is a monophonic song by the fourteenth-century French composer Guillaume de Machaut. It is an example of the genre known as the virelai, one of the fixed formes of the fourteenth century (the others were the ballade and the rondeau). Schrade catalogues this work as Virelai No. 3. This is a relatively early work of Machaut's, dating from the time of his patronage by John of Luxembourg, King of Bohemia.
Machaut is known primarily as a composer of polyphonic music, particularly of the monumental Messe de Notre Dame. However, he also wrote a great deal of monophonic song, much of it rarely performed and researched. Most of his virelais and almost all his lais are monophonic as well as his sole surviving chanson royal and complainte. His monophonic settings tend to be conservative in style, as do his choice of genres (the lai, especially, was rarely composed in the fourteenth century, and Machaut wrote the last known examples of this genre). ~ David Cashman, Rovi
