Gregorian Chant Databaseis is a searchable database of plainchant melodies and texts included in medieval sources and new editions. It serves as a simple tool for searching information on Gregorian chant and other medieval monody including sacred songs. At this time the database contains almost 25.000 records of chant incipits that provide information about text, melody, genre, modus and concordances in new editions and other on-line databases. Some of the records include also hypertext links to facsimiles where a particular chant can be found. The Global Chant Database was developed by Jan Koláček - PhD student of the Institute of Musicology at the Charles University in Prague.
