The Catedral de Salamanca has announced a groundbreaking double CD of Gregorian chant through its label CATHEDRALIS, representing a major milestone in Task 2.3 of the REPERTORIUM project. This release showcases how the project is revolutionizing the recovery of lost medieval music through advanced AI technology.
REPERTORIUM Task 2.3: Digitization and Recovery of Musical Heritage
Task 2.3 of REPERTORIUM focuses on the digitization, cataloging, and transcription of ancient musical manuscripts from European archives. This CD release directly embodies the goals of this task by making recovered Gregorian chants accessible to performers, scholars, and the general public.
The REPERTORIUM project, funded by the European Union’s Horizon Europe programme, applies advanced artificial intelligence techniques to process thousands of Gregorian chants that had been silent for over a millennium. What would traditionally require centuries of painstaking work by human scholars can now be accomplished through AI-assisted optical music recognition (OMR), machine learning, and paleographic analysis.
A Historic Recording
All chants included in the second CD of this double album have been recovered thanks to REPERTORIUM’s AI technology as part of Task 2.3 and represent world premiere recordings—pieces that are being heard for the first time in modern history.
The project is directed by Juan Carlos Asensio Palacios, a key researcher in REPERTORIUM and one of the world’s foremost authorities on plainchant. The performance is executed by the prestigious vocal ensemble Schola Antiqua, which has 40 years of experience in the study and interpretation of Gregorian chant and has participated in REPERTORIUM concerts and recordings.
Preserving Heritage Through Innovation
This release demonstrates Repertorium’s mission: to bridge cutting-edge European technology with centuries-old musical traditions, ensuring that precious cultural treasures are preserved and made accessible for future generations.
The official presentation took place yesterday, on Wednesday, December 3, 2025, at the Catedral de Salamanca.
