The medieval songbook known variously as trouvere manuscript C or the Bern Chansonnier (Bern, Burgerbibliothek, Cod. 389) is one of the most important witnesses to musical life in thirteenth-century France. Almost certainly copied in Metz, it provides the texts to over five hundred Old French songs, and is a unique insight into cultures of song-making and copying on the linguistic and political borders between French and German-speaking lands in the Middle Ages. Notably, the names of trouveres, including several female poet-musicians, are found in its margins, names which would be unknown today without this evidence. However, the manuscript has received relatively little scholarly attention, partly because the songs’ musical staves remained empty for reasons now unknown, and partly because of where it was copied. This collection of essays is the first to consider C on its own terms and from a range of disciplinary perspectives, including philology, art history, literary studies, and musicology. The contributors explore the process of creating the complex object that is a music manuscript, examining the work of the scribes and artists who worked on C, and questioning how scribes acquired and organised exemplars for copying. The peculiarly Messine flavour of the repertoire and authors is also discussed, with contributors showing that C frames the tradition of Old French song from a unique perspective. As a whole, the volume demonstrates how in this eastern hub of music and poetry, poet-composers, readers, and scribes interacted with the courtly song tradition in fascinating and unusual ways.
