Music Theory from Boethius to Zarlino is a companion volume to Music Theory from Zarlino to Schenker: A Bibliography and Guide by David Damschroder and David Russell Williams (Harmonologia, No. 4, Pendragon Press). Like the previous work, the goal of the volume is to create a logically organized introduction to the major theorists of the time and a thorough review of the scholarly work about these writ- ers. While specialists in the history of music theory may find new materials in these pages, this work is primarily designed for the non-specialist as a practical and basic introduction to the treatises, people, and scholarship of Medieval and Renaissance theory. The two major sections of the work are the Dictionary of Theorists which includes individual chapters for approximately one hundred and twenty authors, arranged alphabetically and the Literature Supplement which lists articles, books and disserta- tions which pertain to several Dictionary of Theorists authors and which, therefore, would be inappropriately placed in any one of those chapters. The work begins with a listing of Abbreviations listing short entries used throughout the book for periodicals, series, congress reports, and Festschriften. The work concludes with Indices referenc- ing names, titles, topics, and an approximate chronology of the works cited. - Publisher.
