In the late-eighteenth and nineteenth centuries, some chant reformers ( notably the editors of the Mechlin, Pustet-Ratisbon ( Regensburg ), and Rheims-Cambrai Office-Books, collectively referred to as the Cecilian Movement ) renumbered the modes once again, this time retaining the original eight mode numbers and Glareanus's modes 9 and 10, but assigning numbers 11 and 12 to the modes on the final B, which they named Locrian and Hypolocrian ( even while rejecting their use in chant ).
