Studying Large Plainchant Corpora Using chant21
Pages 40 - 44
Abstract
We present chant21, a Python package to support the plainchant formats gabc and Volpiano in music21, and two large corpora of plainchant. The CantusCorpus contains over 60,000 medieval melodies collected from the Cantus database, encoded in the Volpiano typeface. The GregoBaseCorpus contains over 9,000 transcriptions from more recent chant books in the gabc format. Chant21 converts both formats to music21, while retaining the textual structure of the chant: its division in sections, words, syllables and neumes. We present two case studies. First, we report evidence for the melodic arch hypothesis from the GregoBaseCorpus. Second, we analyze connections between differentiæ and antiphon openings in the CantusCorpus, and show that the systematicity of the connection can be quantified using an entropy-based measure.

Text boundaries do not provide a better segmentation of Gregorian antiphons
DLfM '23: Proceedings of the 10th International Conference on Digital Libraries for MusicologyIt has been previously proposed that syllable and word boundaries in Gregorian chant texts can be used to segment chant melodies in a more meaningful way than segmentation methods that do not take textual information into account, based on how ...
Differentiae in the cantus manuscript database: standardization and musicological application
DLfM '18: Proceedings of the 5th International Conference on Digital Libraries for MusicologyWhen approaching the study of medieval plainchant, one is inevitably confronted with its immensity, spanning several centuries and a wide geographic area. Even at a specific time and place, its notation and liturgy varies depending on the type of ...
A Preliminary Proposal for a Systematic GABC Encoding of Gregorian Chant
DLfM '24: Proceedings of the 11th International Conference on Digital Libraries for MusicologyIn the last years, several approaches have addressed the encoding of the different music scripts used for plainchant. One of these approaches is the GABC format. While being a comprehensive symbolic representation of square notation, the lack of a ...
