Acknowledgements I have been privileged and fortunate to work with Professor Reinhard Strohm, who has supervised this dissertation with enthusiasm, patience and generosity of both his time and ideas. My thanks to him for his support and guidance throughout my postgraduate studies. In spring 1993, I visited Heidelberg University as an ERASMUS student. My thanks to Professor Ludwig Finscher for his time and encouragement at an early stage of this project. Special thanks also to Tim Crawford of King's College London who offered invaluable expertise and assistance in producing the music editions presented in Appendix I. Research for this dissertation was funded by a three-year grant awarded by The Humanities Research Board of the British Academy. I have enjoyed the help and cooperation of librarians and staff at many libraries including: the Music and Humanities Libraries at King's College London, the University of London Library, Senate House, the British Library, the Berlin Staatsbibliothek, the Bayerische Staatsbibliothek in Munich and the BischOfliche Zentralbibliothek in Regensburg. Finally, my thanks to all my friends and especially to my family who have been a constant source of support and encouragement throughout. Abstract Manuscript and printed sources attribute over 50 motets to Henricus Isaac (c. 1450-1517). This study focuses on the transmission, structure and function of Isaac's work in this genre. It begins by considering the implications of recent manuscript research on the dating and attributions of Isaac's motets. Several motets that have been incorrectly attributed to Isaac are newly-identified and the attributions of those motets classified as dubia by Martin Just are also reconsidered. Over half of Isaac's motets are settings of liturgical chant. The study analyses cantus firmus treatment in Isaac's chant settings. New chant sources are identified for three antiphons set by Isaac including the Marian antiphon 'Ave sanctissima Maria'. The influence of both local liturgical traditions and specific polyphonic repertories on Isaac's work is explored through comparison of the melodic versions of chant Isaac sets with contemporary chant sources as well as with contemporary polyphonic settings. The tempo relationship between tempus perfectum (0) and tempus imperfectum diminutum (0) in Isaac's motets is also studied. Comparison of the mensural organisation of motets in which perfect and imperfect time mensurations occur simultaneously with the mensural organisation of works in which the two mensurations appear successively highlights changes in the tempo relationship between 0 and 0. This study prompted a comparative analysis of the mensural organisation of Isaac's through-composed masses. Here, the interpretation of average note values as time series data is explored and new thoughts are offered on the correlation between tempo and rhythmic movement. Finally, the functions of Isaac's motets are considered. Specific contexts in which Isaac's motets were performed may be established through analysis of both their texts and transmission. It can be shown that Isaac's motets functioned as liturgical polyphony, as 'chapel music' and as musical propaganda. The study ends with an exploration of motets that may have originated from commissions. 5 TABLE OF CONTENTS Page VOLUME ONE Abstract 3 Table of contents 5 List of tables, figures and examples 8 Introduction 10 Isaac's motets: sources and attributions Introduction 28 29 Manuscript studies 29 - Munich 3154 35 - Berlin 40021 - Regensburg C. 120 39 The attributions of Isaac's motets 42 - Motets incorrectly attributed to Isaac 50 - Doubtful attributions 59 - Spurious motets 64 - Just's dubia 65 2 Cantus firmus treatment in Isaac's chant settings Introduction 83 Cantus firmus treatment in Isaac's chant settings 87 - Cantus firm us repeated 92 - Cantus firmus in notes of equal value 107 - Free cantus firmus elaborations 110 - Cantus firmus in superius 110 - Cantus finnus in bassus 115 - Migrating cantus firmus 121 - Cantus firmus in tenor and superius 128 - Cantus firmus in imitation 137 - Chant fantasias 142 - Chant settings in motet-like form 148 3 Isaac's chant settings and liturgical traditions: a preliminary study Introduction 164 Consulted chant sources 173 Newly-identified chant sources 177 - Ave sanctissima Maria 177 - Gaude, Dei genitrix 197 - Salve regina 210 Multiple settings of chant cantus firmi 211 - Argentum et aurum 212 - Virgo prudentissima 220 6 4 The tempo relationship between perfect and imperfect time in Isaac's motets Introduction 243 Perfect and imperfect time in Isaac's motets 246 - 0 decus ecclesiae 249 - Salve reginal 252 - Angeli archangeli / Comme femme desconfortée 253 - Optime divino I Da pacem / Sacerdos et pontifex 256 - Quid retribuam tibi, Leo 260 - Virgo prudentissima (a6) 262 - Salve regina II 267 5 The mensural organisation of Isaac's through-composed masses Introduction 273 The relative chronology of Isaac's through-composed masses 279 The correlation between tempo and rhythmic movement in 0 and 0 292 6 Cantus firmus and function in Isaac's motets Introduction 299 The functions of Isaac's motets 304 - Liturgical polyphony 305 - Chapel music 308 - Instrumental-type motets 311 - Musical propaganda 212 Cantus firmus and function 318 - Spiritus sanctus in te: Ludwig Senfi 321 7 VOLUME TWO Appendices I: Music editions 1.
