Chapter 4 explores the memorial aspects of the Latin refrain and its circulation between genres and among works, demonstrating how the Latin refrain and refrain song participate in an extensive, and at times complicated network of textual and musical borrowing, reworking, and repetition. These intertextual and intermusical networks include refrains that are reworked from other genres, most often chant; refrains that are employed structurally across different songs; and refrains that are recycled more freely among songs. Although relying on the written side of the Latin refrain’s transmission, these forms of intertextuality are underpinned by the lived experiences of the individuals and communities who performed, remembered, and wrote down Latin song and refrain; singers, scribes, and compilers are the unnamed agents driving the recycling of Latin refrains. Chapter 4 concludes with a case study of two fourteenth-century sources from an Austrian abbey that considers how the inscription of refrains within this monastic community evidences an evolving, living practice of remembering, singing, copying, and reusing Latin refrains.
