Mille Regretz is a French chanson which in its 4 part setting is usually credited to Josquin des Prez. Josquin's version is in the Phrygian mode. Its plangent simplicity made it a popular basis for reworkings (such as the mass setting by Cristóbal de Morales, and the 6vv (SATTBB) setting by Nicolas Gombert), the variations for vihuela known as "La Canción del Emperador" by Luis de Narváez, as well as more recent sets of variations and threnody. Translations of the song differ in their interpretation of the words 'fache/face amoureuse' in line 2. (variously 'amorous anger' or 'loving face'.)
The authorship of the original as by Josquin is sometimes disputed.
The chanson was said to be a favorite of King Charles I of Spain.
