Gregorio (software)

Gregorio is an open-source software program used for engraving Gregorian chant notation. It is designed for typesetting and producing high-quality musical scores, particularly those that involve Gregorian chants, which are a form of plainchant used in the liturgy of the Roman Catholic Church. The software allows users to create and edit musical scores using a textual input format, which then compiles into visually appropriate notation.
