Melody of the R/ from Solesmes 1957 with minor corrections from Gregofacsimil. Neumes from H. Gloria Patri synthetic. Melody of the V/ critically established from Vat 8737 , Arras 465 and FCo2. This is definitively a proper melody and not an error introduced when copying the typical 7th mode verse tone.

Added si bémol from GFS

Added contrafacta neumes on verse
