Notes to the transcription of the music in RA fragm. 4613
by John Bergsagel
Slurs over the notes indicate the neumes of the original notation; slurs under the notes indicate liquescent neumes. The material within square brackets restores what has been omitted from the abbreviated copy of the manuscript.
Intr. Respice Domine
In liturgical performance the Introit Antiphon Respice Domine would have been repeated after the Gloria Patri. In some instances the Introit Antiphon was also sung between the Psalm Verse and the Gloria Patri. The Introit Respice Domine is in Mode 7. Unlike the common version (e.g., in the Liber Usualis), in which it begins with an upward interval of a 5th, it begins here with an upward 4th, as is also found in the 13th‑C. English Graduale Sarisburiense (facsimile ed., Plainsong and Mediaeval Society, 1894, 156). The notes at iratus that begin the second half of the Psalm Verse, however, are probably a copyist's error and should correspond to those at Sicut erat and et in in the Gloria Patri.

Gr. Respice Domine
The Gradual follows the reading of the Epistle. In liturgical performance the Gradual Respond Respice Domine would have been repeated after the Versus, except when, as here, it is followed immediately by the Alleluia. The Gradual Respice Domihe is in Mode 5. The version here differs in numerous details from the authorized modern editions (e.g., in the Liber Usualis).

Alleluia V. Domine, refugium factus est
The Alleluia follows immediately after the Graduale and precedes the reading of the Gospel. In liturgical performance the Versus, sung by a soloist(s), would (in this case) conclude with the whole choir repeating the long, textless melisma (the neuma or jubilus) at the end of the Alleluia. The Alleluia would then be repeated by the whole choir. Alleluia V. Domine, refugium factus est is in Mode 7. It shows minor differences of detail from the authorized modern version of the Liber Usualis; in the 13th‑C. English Graduale Sarisburiense (facsimile ed., op. cit.) another Alleluia (with Versus Quoniam Deus magnus Dominus) is used for the 13th Sunday after Pentecost.
