D. PA903 CHANT REPERTORIES
1. Antiphons, Tropes, Prosulas, and Prosas
The embellishing chants of the Mass are presented differently in each of the
Aquitanian graduals: tropes appear only in Pa903; antiphons appear in all but the St.
Martial gradual; prosulas and prosas are prominently presented in the St. Yrieix, Gaillac,
and the St. Martial graduals. The tropes of the Proper and Ordinary, listed complete in
Appendix A4-2, make their first appearance as a group outside of Pa903, with notations
of the feasts and chants to which each of the tropes applies. Similarly, the complete
repertory of prosulas and prosas of Pa903 is listed for the first time under one cover in
Chapter IV, including the feasts and chant genres for which they were written and
concordances with the other Aquitanian graduals.
These repertories, however, show that there are structural anomalies in Pa903. In
the case of the tropes, a small number were copied with cues to Gregorian Mass chants
that were not included in the neo-Gregorian formularies of their assigned feasts. The
tropes for the prominent feasts of Aredius, Benedict, the Finding of the Cross, Finding of
St. Stephen and Vigil of St. Martin were composed for Gregorian chants, but the
formularies for these Masses in the gradual are neo-Gregorian. In addition a group of
tropes was assigned to chants that are not included in the gradual. The miss-assigned
tropes are instead compatible with the Gregorian chants for a common of saints (one
martyr, multiple martyrs, and so on) that is missing in the manuscript.
Similarly, some of the alleluia prosas (including the Aredius prosas) explicitly
include an alleluia that was not used for the feast to which it was assigned, while others
were assigned to a feast that does not appear in the gradual. A further feature of these
chants is that Pa903 transmits prosulas that are overwhelmingly concordant with one
