This is the third in a set of four collections of articles by Michel Huglo to be published in the Variorum series. It brings together the studies of Gregorian chant and of later monophonic and polyphonic additions to the earlier repertory that occupied Huglo in the second phase of his research. Represented here are articles on the Kyrie, the introit tropes of St-Gall, an elegy for William the Conqueror (d. 1087), the versus by Venantius Fortunatus for the cathedral of Paris, the liturgical dramas of Fleury, early organum, the Mass of Tournai, and, finally, the Requiem by Eustache Du Caurroy. Ce volume des articles de Michel Huglo est le troisième de la série de quatre dans la collection Variorum. Il réunit des études sur le chant grégorien et sur les additions de pièces monodiques ou polyphoniques faites au répertoire primitif, sujets qui ont occupé Michel Huglo dans la seconde phase de sa carrière de chercheur. Dans ce volume, le lecteur trouvera des articles sur le Kyrie, les tropes d'introït de St-Gall, l'élégie pour Guillaume le Conquérant (d. 1087), les versus de Venance Fortunat pour la cathédrale de Paris, les drames liturgiques de Fleury, les débuts de l'organum, la Messe de Tournai, et finalement le Requiem d'Eustache Du Caurroy.

The origin and development of Western plainchant, and of the genres of liturgical book in which it is recorded, have occupied Michel Huglo throughout his long career, which has taken him to libraries in every corner of Europe and the United States. This volume, the first in a set of four to appear in the Variorum series, brings together analyses of manuscripts dating from the 9th to the 13th century, including Huglo's pathbreaking studies of the antiphoner of Compiègne, the first troper-prosers, and of alleluia lists as clues to place of origin. The consequences of the Treaty of Verdun (843) for the diffusion of the plainchant repertory, research in medieval musicology in the 20th century, the utility of codicology for musicological manuscript studies, and the critical edition of the Gregorian antiphoner are addressed in other studies included here. Les origines et le développement du plain-chant en Occident et l'étude des genres de livres liturgiques qui le contiennent ont occupé Michel Huglo durant sa longue carrière et l'ont conduit à visiter des bibliothèques partout en Europe et aux Etats-Unis. Ce volume, le premier d'une série de quatre dans la collection Variorum, comprend des analyses de manuscrits du neuvième au treizième siècle, notamment des études novatrices relançant les recherches sur l'antiphonaire de Compiègne, les premiers tropaires-prosaires et les listes d'alleluias comme moyen d'identification des manuscrits de chant. Les conséquences du traité de Verdun (843) pour la diffusion du répertoire de plain-chant, les recherches en musicologie médiévale au XXe siècle, l'application des méthodes de la codicologie à l'étude des manuscrits notés, et l'édition critique de l'Antiphonaire grégorien forment les sujets d'autres études réunies dans ce volume.

The years 1590-1890 comprised a period of intensive activity in the realm of Gregorian chant, marked by two major and opposing series of fundamental changes to the repertoire. This vitality notwithstanding, only a small handful of studies provide information about chant in this period. The present monograph and edition seek to remedy this lacuna in our knowledge with respect to chants for the Mass Proper. It presents the first large-scale account of the various repertoires involved, together with transcriptions from selected primary sources. It offers also the first extensive listing of our primary printed sources. Earlier studies have indicated the most basic features of post-Tridentine revisions of chant, but these generalizations remain jejune without access to readings from major sources. These have largely been lacking. Inasmuch as no single work can offer both a panorama of the period as a whole and a detailed study of individual sources in their entireties, the author has chosen to focus in the initial and largest part of this book on five complete Mass Propers and a group of individual chants. In this fashion the reader is brought into touch with the variety of early editorial revisions of chant and also with contemporary sources that sought to adhere to previous medieval traditions. Later chapters deal with the plainchant musical of Nivers, the virtually unknown repertories of Neo-Gallican chant, aspects of chant during the 18th century, and the major monuments of 19th-century chant that preceded the return to medieval chant sources represented by the editions issued by the Abbey of Solesmes. Issued in two physical pieces. Part 1 has text with Audio CD performances of some of the Mass Propers discussed in the book. Part 2 has complete comparative music examples of Mass Propers discussed in the book, examples that detail variations between the various traditions transmitted in the sources.

This is the final volume in the set of four collections of Michel Huglo's articles to be published in the Variorum series, and focuses on medieval music theory. The point of departure for Huglo's research was his doctoral dissertation on tonaries, published in 1971: as a consequence, he studied the manuscripts of music theory concerning plainchant, and, later, those with writings on music by authors of Late Antiquity as well as the Liber glossarum, with its many definitions of musical terms. In this volume, certain articles consider the interpretation or dissemination of texts, instruction in the art of plainchant, and musical instruction at the university. Others concern the manuscripts of St Augustine's De musica and of the writings of Calcidius, Macrobius, Helisachar, Hucbald, Gerbert of Aurillac, Abbo of Fleury, John of Afflighem, and Hieronymus de Moravia, amongst others. The volume closes with a bibliography of Michel Huglo complementing that published in 1993 and a summary list of his reviews of books on music and liturgy. Ce volume des articles de Michel Huglo termine la série de quatre dans la collection Variorum. Il est centré sur la théorie musicale médiévale. Le point de départ des recherches de Michel Huglo sur la théorie musicale du Moyen Âge est formé par sa thèse sur les tonaires, éditée en 1971: en consequence il etudia les manuscrits de theorie musicale concernant le plain-chant et, plus tard, les auteurs de l'Antiquité tardive et le Liber glossarum qui contient des définitions de nombreux termes musicaux. Dans ce volume, certains articles traitent de l'interprétation ou de la dissémination des textes, des instructions sur l'art du chant, et sur l'enseignement de la musique à l'Université. Ils concernent les manuscrits du De musica d'Augustin, de Calcidius, Macrobe, Helisachar, Hucbald, Gerbert d'Aurillac, Abbon de Fleury, Jean d'Afflighem, Hieronymus de Moravia, et d'autres auteurs. Le volume se termine par une bibliographie de Michel Huglo complétant celle publiée en 1993 et ​​une liste sommaire de ses recensions d'ouvrages sur la musique et la liturgie.
