The Critical Nexus confronts an important and vexing enigma of early writings on music: why chant, which was understood to be divinely inspired, needed to be altered in order to work within the then-operative modal system. To unravel this mystery, Charles Atkinson creates a broad framework that moves from Greek harmonic theory to the various stages in the transmission of Roman chant, citing numerous music treatises from the sixth to the twelfth century. Out of this examination emerges the central point behind the problem: the tone-system advocated by writers coming from the Greek harmonic tradition was not suited to the notation of chant and that this basic incompatibility led to the creation of new theoretical constructs. By tracing the path of subsequent adaptation at the nexus of tone-system, mode, and notation, Atkinson promises new and far-reaching insights into what mode meant to the medieval musician and how the system responded to its inherent limitations.
Through a detailed examination of the major musical treatises from the sixth through the twelfth centuries, this text establishes a central dichotomy between classical harmonic theory and the practices of the Christian church. Atkinson builds the foundation for a broad and original reinterpretation of the modal system and how it relates to melody, grammar, and notation. This book will be of interest to all musicologists, music theorists working on mode, early music specialists, chant scholars, and medievalists interested in music.

The influence of Rome on medieval plainsong and liturgy explored in depth. Containing substantial new studies in music, liturgy, history, art history, and palaeography from established and emerging scholars, this volume takes a cross-disciplinary approach to one of the most celebrated and vexing questions about plainsong and liturgy in the Middle Ages: how to understand the influence of Rome? Some essays address this question directly, examining Roman sources, Roman liturgy, or Roman practice, whilst others consider the sway ofRome more indirectly, by looking later sources, received practices, or emerging traditions that owe a foundational debt to Rome.

Comparative studies of medieval chant traditions in western Europe, Byzantium and the Slavic nations illuminate music, literacy and culture. Gregorian chant was the dominant liturgical music of the medieval period, from the time it was adopted by Charlemagne's court in the eighth century; but for centuries afterwards it competed with other musical traditions, local repertories from the great centres of Rome, Milan, Ravenna, Benevento, Toledo, Constantinople, Jerusalem, and Kievan Rus, and comparative study of these chant traditions can tell us much about music, liturgy, literacy and culture a thousand years ago. This is the first book-length work to look at the issues in a global, comprehensive way, in the manner of the work of Kenneth Levy, the leading exponent of comparative chant studies. It covers the four most fruitful approaches for investigators: the creation and transmission of chant texts, based on the psalms and other sources, and their assemblage into liturgical books; the analysis and comparison of musical modes and scales; the usesof neumatic notation for writing down melodies, and the differences wrought by developmental changes and notational reforms over the centuries; and the use of case studies, in which the many variations in a specific text or melodyare traced over time and geographical distance. The book is therefore of profound importance for historians of medieval music or religion - Western, Byzantine, or Slavonic - and for anyone interested in issues of orality and writing in the transmission of culture.
