Baude Cordier (born c. 1380 in Rheims, died before 1440) was a French composer from Rheims; it has been suggested that Cordier was the nom de plume of Baude Fresnel. Cordier's works are considered among the prime examples of ars subtilior. In line with that cultural trend, he was fond of using red note notation, also known as coloration, a technique stemming from the general practice of mensural notation. The change in color adjusts the rhythm of a particular note from its usual form. (This musical style and type of notation has also been termed "mannerism" and "mannered notation.")
- some are in the rhythmically complex late fourteenth-century French style of ars subtilior, such as "Amans amés secretement" (Lovers, love discretely).
- others are simpler, with greater emphasis on lyrical melody, such as "Belle, Bonne, Sage", also transcribed in HAM, and characterized with "Amans" as a rondeau.
- the love song "Belle, Bonne, Sage" ("Beautiful, Good, Wise"). The manuscript is in the shape of a heart.
- a circular canon "Tout par compas suy composés" ("With a compass was I composed")—more eye music, in which the manuscript is written in a circle.
His mass movement in the Apt MS is in the later, simpler fifteenth-century style.
