RILM abstract:"A number of thorough-bass realizations in modern editions of early-17th-c. Italian music are compared with the rules for harmonization, voice leading, musica ficta, and performance practice as laid down in treatises from the same period. Early pieces often should be harmonized differently from how they have been in modern editions. There are also many possibilities such as playing 5-6-5-6 sequences, doubling the bass in octaves, and adding dissonances in certain progressions and allowing false relations, that have hardly been used or have been avoided because they were not thought to be allowable.(Tashiro, Mimi)"
