This book investigates how the Old Hispanic chant, specifically the genre of the sacrificium, functioned as a primary vehicle for Christian formation and the construction of communal identity in early medieval Iberia. Rebecca Maloy, a specialist in medieval music, utilizes a combination of liturgical analysis, patristic study, and musicological examination to argue that these chants were not merely functional musical accompaniments but sophisticated tools for biblical exegesis. By examining the intersection of text and melody, the author demonstrates how the Visigothic church used these liturgical performances to shape the theological understanding and social cohesion of its practitioners.

Scholars in the field of medieval musicology identify this work as a rigorous and essential study for understanding the liturgical soundscapes of early medieval Iberia. Readers frequently note the academic density of the prose, which assumes a foundational knowledge of both music theory and ecclesiastical history.
