A rich manuscript tradition has facilitated numerous studies of Aquitanian sacred music, but to date most previous research has focused on one particular facet of the repertoire, often in isolation from its cultural context. This study seeks to view Aquitanian musical culture through several intersecting sacred and secular concerns and to relate the various musical traditions to the region's broader societal forces. Saint-Martial in Limoges and Toulouse, two musical and cultural centers, illustrate the wider cultural context in Aquitaine, and a survey of select manuscripts shows the development of a musical tradition. An examination of three disparate pieces shows that the repertoire as a whole is a more unified part of Aquitanian culture than previously recognized. / Committee in Charge: Dr. Lori Kruckenberg, Chair; Dr. Marc Vanscheeuwijck; Dr. Marian Smith
