Abstract
In the thirteenth-century, the city of Paris witnessed the birth of the University, the gradual penetration of the new philosophical paradigm of Aristotelianism and the emergence of a new theoretical discourse dealing with the measurement and notation of musical time. Scholars have attempted to find correlations between these three distinct phenomena. Focusing on music theory sources and on other indirect testimonies, they have never satisfactorily approached the central question of the teaching of music in the Arts faculty of Paris. The objective of the present study is precisely to explore this terra incognita.
