CANTUS: A database for Latin ecclesiastical chant is a free online resource that assembles and publishes indices of over 380,000 chants found in manuscript and early printed sources for the liturgical Office. The database is searchable by text incipit, keyword, Corpus Antiphonalium Officii identification number, or Liturgical occasion.
CANTUS is supported by the University of Waterloo and The Andrew W. Mellon Foundation. Terence Bailey serves as the project’s director.
