Composers of the Early Middle Ages (500–1000) almost exclusively concerned themselves with sacred music, writing in forms such as antiphons, hymns, masses, offices, sequences and tropes. Most composers were anonymous and the few whose names are known were monks or clergy. Of the known composers, the most significant are those from the Abbey of Saint Gall school, particularly Notker the Stammerer (Notker Balbulus); the Saint Martial school and its most prominent member, Adémar de Chabannes; and Wipo of Burgundy, to whom the well-known sequence "Victimae paschali laudes" is usually attributed.
