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", see Bibliography).
