Bruges (?) composition sketches by Flemish polyphonists

This collection comprises one hymn, one chanson, sketches and drafts for six chansons, and one instrumental composition without text. These compositional sketches by Flemish polyphonists are an extraordinary rarity. The folios offer us a glimpse over the shoulder of an anonymous copyist/composer, providing insight into the creative process. These documents reveal that the composer envisioned a comprehensive concept, with the musical parts being developed not only sequentially but also concurrently. At one point, a semi-score is even employed. Despite its poor condition and the careless handwriting, this document is of immeasurable scientific value for understanding the composition process. Additionally, it marks the introduction of the new Parisian chanson into the Low Countries, signifying an important cultural transition.
