Ockeghem's Requiem is unusual both compared to his other works, and to other settings of the Requiem. Stylistically, the movements are all very different from each other; each uses a paraphrase

The Chigi codex is a music manuscript originating in Flanders. According to Herbert Kellman, it was created sometime between 1498 and 1503, probably at the behest of Philip I of Castile. It is currently housed in the Vatican Library under the call number Chigiana, C. VIII...

. Since this collection seems to have been intended as a complete collection of Ockeghem's music, the absence of these movements was probably due to their either not being available to the copyist, or not available in the condition required. Blank opening sections in the codex also imply that at least one other movement, probably a three-voice setting of the Communion in a more sedate style recalling the opening Introit, was originally intended to close the work. Two other Masses in the codex, Ma maistresse and Fors seulement appear to be missing movements as well.

The style of the work is austere, as befitting a setting of the Mass for the Dead; indeed the lack of polyphonic settings of the Requiem until the late 15th century was probably due to the perception that polyphony was insufficiently sober for such a purpose. Portions of the work, especially the opening Introit, are written in a style reminiscent of the first half of the 15th century, with the chant in the topmost voice, and the accompanying voices singing mostly in parallel motion in a fauxbourdon

-like manner. Within the movements, there are subsections for two or three voices which provide contrast with the fuller four-voice textures that surround them and provide a sense of climax. This procedure is typical of Ockeghem.

, a monarch to whom Ockeghem owed a debt of gratitude, and for whom he would likely have composed a Requiem. (If this date is correct, the Requiem could predate Dufay's, the date of which is also speculative.) Others have suggested that Ockeghem may have composed it instead for the death of Louis XI
