Summary Scriptor, Cantor & Notator is an innovative multi-author project dealing with the complex interconnections between learning, writing and performing chant in the Middle Ages. A number of different methodological approaches have been employed, with the aim of beginning to understand the phenomenon of chant transmission over a large geographical area, linking and contrasting modern definitions of East and West. Thus, in spite of this wide geographical spread, and the consequent variety of rites, languages and musical styles involved, the common thread of parallels and similarities between various chant repertoires arising from the need to fix oral repertories in a written form, and the challenges involved in so doing, are what bring this wide variety of repertoires and approaches together. This multi-centric multi-disciplinary approach will encourage scholars working in these areas to consider their work as part of a much larger geographical and historical picture, and thus reveal to reader and listener more, and far richer, patterns of connections and developments than might otherwise have been suspected. Scriptor, Cantor & Notator is published in two books. The first, The Materiality of Sound in Chant Manuscripts in the West, brings together articles on several different families of early music scripts in the Latin West and provides a vividly diverse picture of some of the best current scholarship on the various types of ancient and medieval musical notation.
