that can be deciphered with reasonable certainty', and except that the five fragmentary liturgical works from the former Chartres MS 109 (the latest of the Chartres fragments) are also included, it, too, deals solely with the Aquitanian and Calixtine repertories.
The lack of slurs or genuine ligatures corresponds to the generally detached nature of the grouped notes in the Aquitanian (though not in the Calixtine) sources.
The author does not shrink from finding fault with other writers on such matters; yet he can point out the coincidence of accent and quantity at the end of each line of the Calixtine poem 'Jacobe sancte' without noticing that the whole piece (if one overlooks the unconventional scansion of the first word) is in Leonine hexameters.
