This volume stems from a research project on medieval and sixteenth-century fragments with music carried out at CESEM?Centre for the Study of the Sociology and Aesthetics of Music, Lisbon Nova University, between 2021 and 2024, as well as from an international colloquium on fragmentology held in Cascais, Portugal, in July 2023. It brings together twenty studies that address a varied range of disjecta membra, including loose folios from dismembered manuscripts, mutilated musical-liturgical codices, incomplete sets of part-books, truncated musical settings, and even the remains of a historic organ. The aim is to invest these materials with significance beyond their condition as fragmented cultural artefacts by exploring their texts, contexts, meanings, trajectories and, when appropriate, proposing methods for their reconstitution.
