Cross-references Between Tonaries During The Reforms Between The 10th and The 13th Century

Nevertheless the tonary was not replaced by these manuscripts. While the first generation of notated manuscripts became less and less readable until the end of the 10th century, the production of tonaries as useful appendix highly increased, especially in Aquitania, the Loire valley (Île-de-France) and Burgundy. Probably the oral tradition of the melody was no longer properly working since the early 11th century, or there was still a need in a lot of regions to teach certain cantors an unknown tradition, or the tradition itself had to change under certain innovations of cantors who were in charge of an institutional reform. Studies of the reforms of various regions in Spain, Germany, Italy, and France have found evidence for all these cases whatever was the centre of each reform which had taken place between the late 10th and the 12th centuries. The monk Hartvic added some Dasia signs for certain differentiae as a kind of rubric or comment on the margin (Tonary of St. Emmeram, Regensburg). He knew them from the treatises Musica and Scholica enchiriadis which he copied in this manuscript, and thus he discovered a new way of using them: as an additional explanation or second pitch notation interpreting the adiastematic neumes.
