Dominique Crochu

Dominique Crochu is a medievalist, fellow liturgical connoisseur and co-director of the Musique Médiévale network. He began working with monks of Solesmes in 1980, where he learnt semiology at the musical Paleography workshop. He soon specialised in not yet published Old Font Gregorian repertory, especially the Office of Matins, for which, after the French Revolution, the habit was taken to recite instead of sing. His research allowed a decisive advance concerning the very delicate problem of the interpretation of B flat in Gregorian chant. He has collaborated, since 2005, with Dominique Gatté. Together, they have listed more than 8000 manuscripts and printed sources from the fifth to the eighteenth century. He also worked with Alberto Diaz-Blanco to digitalise and restore more than one thousand Gregorian vinylic, shellac and magnetic supports.
