The Saint Martial School was a medieval school of music composition centered in the Abbey of Saint Martial, Limoges, France. Most active from the 9th to 12th centuries, some scholars describe its practices, music, and manuscripts as 'Aquitanian'. It is known for the composition of tropes, sequences, and early organum. In this respect, it was an important precursor to the Notre Dame School. Adémar de Chabannes and his nephew Roger de Chabannes were important proponents of this school. History of the Abbey Saint Martial de Limoges Many of the modern musicological studies concerning a "Saint Martial School" focus on four manuscripts with remarkably innovative compositions for the 12th century. It is often assumed that these fragments derived from different Southern French monasteries, despite the lack of cantor attributions in the rubrics. However, Sarah Fuller has suggested that this may not be the case, discussing the "myth of a Saint Martial school", where she suggests that the fragments are rather a collective activity of the Abbey's librarians than a didactic activity of the Abbey's cantors. These manuscripts (F-Pn lat. 1139, 3549, 3719, and GB-Lbl Add MS 36881) were, it would seem, more likely collected and bound together by the librarian Bernard Itier, than composed or compiled at St Martial itself. Despite the concordances between these manuscripts, the collection includes many variants. The repertory combines modern forms of poetry with modern forms of musical composition, consisting of settings of proses, tropes, sequences, liturgical dramas, and organa. Even a polyphonic setting of an epistle recitation survives as florid organum. Other modern musicological studies have attempted to identify unifying centre for these sources, such as Cluny rather than Limoges, and with reference to the Cluniac Monastic Association, Fleury and Paris (especially the Notre-Dame School), the Abbey of Saint Denis, and the Abbey Saint-Maur-des-Fossés. Questions about periphery and centre may be answered by the research of political and church history relative to Cluny. In contrast to Fuller's study, James Grier's recent examination of earlier monophonic Proser-Sequentiaries suggests that they were created in the scriptorium of the Abbey Saint-Martial 100 years earlier (than the fore-mentioned fragments including polyphonic compositions), explicitly for liturgical use at Limoges, by Roger and Adémar de Chabannes. The concept of a local school of cantors who documented their innovations in newly designed liturgical books with the libellum structure—later imitated elsewhere (even in the Parisian Magnus liber organi)—is therefore still credible; at least
