Information on differentiae

The original Cantus index categorizes the differentia in this manuscript by their last note and an arbitrarily assigned number within each mode. Slight variations, including abbreviations, are indicated by a lowercase suffix (e.g., D2, D2a).

Differentiae appear in their complete six-syllable form and abbreviated to the last two syllables, "Amen." Abbreviated differentiae are indexed as though they were complete in the differentiae Database.
