Abstract
This article presents an initial survey of the cantus fractus repertory in medieval musical- liturgical sources from South Tyrol, a German-speaking region in northern Italy that borders Austria. Most of the cantus planus and cantus fractus sources found in South Tyrol lay previously unknown in the region’s archives and libraries, and were not catalogued or indexed. A research project carried out over the last fourteen years by the Free University of Bolzano/Bozen, devoted to chant sources of the eleventh-nineteenth centuries preserved in the region, has brought to light a considerable corpus of both manuscripts and prints. Nine medieval manuscripts contain chants—mainly Glorias, Credos, and tropes—fully notated as cantus fractus. In addition to these, the article discusses some chants with notational features that suggest rhythmical performance.
