Nulla talis comparatio est, sed sunt lapides pretiosi in illa.
The new database by IRHT (INSTITUT DE RECHERCHE ET D'HISTOIRE DES TEXTES), COMPARATIO, relates to the liturgical chants of the Office, preserved in latin medieval manuscripts. Its particularity is to give not only the text, but the music of these songs. They are transcribed from manuscripts of various origins because the singing of the Office is significantly less standardized than that of the Mass: the different regions and the different religious orders present significant variants, both in music and in the text. The study of these variants thus enables the reader to direct his research towards this or that origin. Each song in this database - currently about three hundred - is documented on average by about twenty transcriptions extracted from manuscripts originating from France, Germany, Italy and Central Europe.
