The fifteen studies assembled here grew out of research on south-Italian ordinary chants and tropes for the multi-volume series Beneventanum Troporum Corpus II, edited by John Boe in collaboration with Alejandro Planchart. In the present essays, clerical and ordinary chants and tropes of the Mass (especially when derived from paraliturgical hymns and poems), certain aspects of chant notation and particular facets of the old Beneventan and the old Roman chant repertories are examined in relation to the three main cultic centres of the Italian south - Benevento, Montecassino and Rome - and as they relate to their European context, namely Frankish and Norman chant and the varieties of chant sung in Italy north of Rome. The volume includes one previously unpublished study, on the Roman introit Salus Populi.

After the imposition of Gregorian chant upon most of Europe by the authority of the Carolingian kings and emperors in the eighth and ninth centuries, a large number of repertories arose in connection with the new chant and its liturgy. Of these repertories, the tropes, together with the sequences, represent the main creative activity of European musicians in the ninth, tenth, and eleventh centuries. Because they were not an absolutely official part of the liturgy, as was Gregorian chant, they reflect local traditions, particularly in terms of melody, and more so than the new pieces that were composed at the time. In addition, the earlier layers of tropes represent, in many cases, a survival of the pre local pre Gregorian melodic traditions. This volume provides an introduction to the study of tropes in the form of an extensive anthology of major studies and a comprehensive bibliography and constitutes a classic reference resource for the study of one of the most important musico-liturgical genres of the central middle ages.
