A second medial mode Palestinian chant in Old Roman, Beneventan and Frankish sources

Chants based on Crucem tuam in the second medial mode are examined in Greek, Slavonic and Latin sources. Central to the discussion is the role of Jerusalem in the dissemination of the modal system. On the Latin side, the emphasis is on Old Roman melodies, showing how they reproduce the prototypes more faithfully than Beneventan or Frankish melodies. The analysis does not support certain conclusions regarding the origins of the modal system and the relationship of Old Roman and Gregorian melodies advanced by Robert Snow, Helmut Hucke and Leo Treitler.
