The REPERTORIUM project is pleased to share news of a major initiative from one of its key team members, Association Musicologie Médiévale, which is co-organizing the upcoming Gregorian Chant Session 2025 with the Abbey of Saint-Pierre of Solesmes. Taking place from July 6 to 11, 2025, this in-depth session invites musicians, scholars, and chant enthusiasts to explore Gregorian chant at the very abbey where its modern revival began—a site deeply rooted in musical tradition, liturgical heritage, and scholarly research.
This year’s session offers far more than a historical retreat. While grounded in the enduring practices of chant, it will also spotlight cutting-edge research and technological perspectives, exploring how Gregorian chant continues to evolve in today’s musicological and digital landscape. In addition to its central role in REPERTORIUM, Association Musicologie Médiévale is also part of the team behind Neumz, the world’s largest digital project for Gregorian chant—a collaboration that reinforces the link between tradition and innovation.
What to Expect in 2025
The 2025 session brings together an exceptional team of international instructors and scholars. Participants will benefit from:
- Workshops and lectures focused on modality, psalmody, neume notation, and chant transcription—combining theoretical exploration with hands-on engagement.
- A new research-driven approach to modality, led by Dominique Crochu, which will explore melodic restitution, the role of B-flat, and the interpretation of manuscript evidence in light of recent discoveries.
- Historical perspectives on the development of chant, including a closer look at Saint Chrodegang of Metz, whose role in shaping early chant helped lay the foundations for the practices later revived by Dom Guéranger.
- Practical instruction tailored to both musicians and researchers, with sessions on rhythm, phrasing, and the dynamic interaction between melody and text.
This year’s program also introduces a dedicated English-language course track—a first for the event—broadening access and inviting new international audiences to participate in the shared work of preserving and advancing chant traditions.
Bridging the Past and Future of Chant
The Gregorian Chant Session 2025 reflects a broader vision shared by its organizers: to foster a living tradition that speaks not only to history but to today’s global musicological and technological communities.
As part of both REPERTORIUM and Neumz, Association Musicologie Médiévale brings a unique perspective to this endeavor. Their work spans chant performance, scholarly editing, paleographic research, and digital accessibility, bridging academic inquiry with real-world tools for transmission and education.
Neumz, for instance, offers the full cycle of Gregorian chant recordings alongside aligned texts, translations, and notated scores—an unprecedented resource for performers, developers, and researchers alike. The Gregorian Chant Session thus serves not only as a learning experience, but also as a platform where technological innovation and manuscript-based research converge.
Far from being solely a liturgical or devotional gathering, the 2025 session is a multidisciplinary initiative at the crossroads of music history, pedagogy, and digital humanities. With the resources of the Atelier de Paléographie Musicale at Solesmes, and the input of contributors deeply engaged in both chant studies and digital documentation, participants will have rare access to the intellectual and material foundations of the chant tradition.
