Codex Sangallensis 381: The title page of Notker's letter to Lantbert

The Codex Sangallensis 381 (Signature Cod. Sang. 381) is an early medieval music manuscript, produced in the abbey of St. Gallen and stored in the Abbey Library in St. Gallen. The manuscript is known for its exhaustive collection of so-called tropes, verses, and sequences. Together with the Cod. Sang. 484, this manuscript makes an important contribution to one of the most exhaustive collections of such compositions in the East Frankish kingdom and thus plays an important role in the history of music.
