This is the third volume of the three Mangon Choirbooks, containing mainly antiphons, canticles and hymns by various composers, almost exclusively by Mangon. Dates and attributions of pieces are given in inventory when present. The manuscript was copied in blackish-brown ink by one large, very neat hand (probably Johannes Mangon) in an elegant minuscule, the same as that of Choir Books I and II; four additional hands are found in the codex:

• Scribe 2 (58v–59r) is the same as that of Scribe 2 in Choir Book II, i. e., probably that of Lambertus de Monte.

• Scribe 4 (123v–124r) is sixteenth-century — though the attribution to the fragment on these leaves is to Guilelmus, the hand is not the same as that of - Scribe 3 in Choir Book II.

• Scribe 5 (33v–34r, 44v–45r, 125v and 139r) is a baroque cursive, probably that of a late seventeenth- or early eighteenth-century succentor.

• Scribe 6 is a seventeenth-century scribe who recopied the presumably decaying fol. 176r, which contains the altus and bassus parts for Mangon’s Vidi aquam.
