Saint Martial school

The Saint Martial School was a medieval school of music composition centered in the Abbey of Saint Martial, Limoges, France. Most active from the 9th to 12th centuries, some scholars describe its practices, music, and manuscripts as 'Aquitanian'.^[1] It is known for the composition of tropes, sequences, and early organum. In this respect, it was an important precursor to the Notre Dame School. Adémar de Chabannes and his nephew Roger de Chabannes were important proponents of this school whose hands had only be recently discovered by studies of James Grier between 1995 and 2005. They invented a local variant of a vertically precise organisation of notation and a new form of local tonary, they reorganised existing chant manuscripts, and they developed the libellum structure of a new type of sequentiary troper whose organisation was new at their time, but played a key role for the Saint Martial school.
