The Gregorio Project: Open-Source Tools for Gregorian Chant Notation (gregorio-project.github.io)

• Advanced TeX-based typesetting engine for neumes
• GPL compliance supports open cultural archiving
• Standardization of liturgical musical notation

"The Gregorio project provides a robust, GPL-licensed software ecosystem for typesetting Gregorian chant. By leveraging TeX technology, it enables researchers and musicians to digitize and preserve ancient liturgical music with high typographical precision. The platform ensures that complex neume-based notations remain accessible in modern digital environments, supporting the resilience of European cultural heritage through open-source infrastructure."
