Differentiae are not consistently notated in this manuscript, but indicated by tonary letters, some of which are trimmed off. A later hand added in many of the differentiae (notated) in the margins of the manuscripts.
The tonary letters (in the differentiae field of the Cantus index for this manuscript) were copied from Omlin's Die Sankt-Gallischen Tonarbuchstaben.
