Differentiae Database

The Differentiae Database provides basic analytic tools for the cross-manuscript study of differentiae and a standardized means for identifying differentiae in manuscript indices. To date, the database includes differentiae from 161 manuscripts, which are fully indexed in the Cantus Database

There are two main intended uses of the Differentiae Database:

  1. Researching differentiae, tonaries, antiphoners, antiphons, psalms, etc.
  2. Indexing any manuscript that contains differentiae

See the About page and its subsidiaries for more information on the project and how to use the database. If you would like to contribute to the database, please see the Contribute page and Contact the project director (Rebecca Shaw).
