The Gregorio project

The Gregorio project offers tools for typesetting Gregorian chant. These tools include:

• gabc: a notation for representing Gregorian chant using ASCII characters
• GregorioTeX: a TeX style for typesetting scores
• a software application to convert from gabc to GregorioTeX

Together, these tools, added to a TeX installation, allow the user to engrave beautiful Gregorian chant scores.

The Gregorio project consists of 100% free software.

This website contains an introduction, documentation and tutorial for Gregorio versions 3.0 and later. For information on older versions, please see the old website.
