Codex Sangallensis 381
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 extensive collection of so-called tropes, verses, and sequences. Together with Cod. Sang. 484, this manuscript is an important contribution to one of the most extensive collections of such compositions in the East Frankish kingdom and thus plays an important role in the history of music.
