This antiphoner has several interesting features. The first is the tone for the Liber generationis (21r), near the end of Christmas Matins (cf. Cambrai XVI C 4, 11r). There are three prosulae for the "Fabricae mundi" melismas (19v) and also a prosula for the responsory "Sancta et immaculata" (20v)--all to be performed during Christmas Matins. The Offices for Lupus (ff. 99v-102v) and Paula (ff. 126r-129r) contain responsories that have particularly long melismas. (For a fuller discussion of the melodies of these responsories, please see Steiner, "Some Melismas," below.) Differentiae are assigned arbitrary numbers. Each chant not found in CAO has been assigned an arbitrary number prefixed by "sen."
