The Artist:
Guillaume de Machaut was a medieval French poet and composer. He is a part of the musical movement known as the ars nova. Machaut helped develop the motet and secular song forms (particularly the lai and the formes fixes: rondeau, virelai and ballade). Machaut wrote the Messe de Nostre Dame, the earliest known complete setting of the Ordinary of the Mass attributable to a single composer.
Info:
"Douce Dame Jolie", sometimes referred to only as 'Douce Dame', is a song from the 14th century, by the French composer Guillaume de Machaut. The song is a virelai, belonging to the style ars nova, and is one of the most often heard medieval tunes today. The lyrics sing to a 'Sweet, lovely lady' who, alas, does not return the singer's affections.
