Dr. DiCenso's work within Medieval music is driven by an interest in the history of the liturgy during the Carolingian era--at the precise moment when Gregorian chant was first written down. Focusing his work on the earliest surviving sources of Gregorian chant, he is particularly interested in the history of liturgical manuscripts and what they reveal about the relationship between music, liturgy, and culture in the early Middle Ages. He is currently working on a new edition of the earliest sources of chant for the Mass and a number of articles related to these sources.
