Provides insight into the world of the Carolingian monks and clerics who created the Liturgy of the Hours. 

Filling in the Gap recounts the creative process behind a specific part of the Gregorian Office repertoire that has not been addressed so far. By linking historical and liturgical evidence with musical analysis, the study opens new avenues for grouping manuscripts and interpreting their interrelationships. The catalogue of melodies included in this volume contains transcriptions of the post-Pentecost antiphon repertoire from twenty-four manuscripts across Western Europe.

David Eben is professor of Gregorian chant at the Institute of Musicology of Charles University and the artistic director of Schola Gregoriana Pragensis.
