O'Neill, Mary. 2006. Courtly Love Songs of Medieval France: Transmission and Style in the Trouvere Repertoire. Oxford and New York: Oxford University Press. Reviewed by Susan Boynton Mary O'Neill's book makes a valuable contribution to our understanding of an important monophonic repertory that has received relatively little atten­ tion from musicologists, despite its preservation in numerous manuscripts. The reasons for this neglect are well known: scholarship on the music of the trouveres has generally addressed their songs alongside or in relation to those of the troubadours. Consequently, the trouvere corpus is often viewed through the lens of a historiography that typically privileges the troubadours because of their chronological priority, casting the trouveres as derivative imitators. O'Neill seeks to understand the trouveres on their own terms. Given the wealth of melodies in medieval manuscripts of trouvere poetry (many in multiple versions), a monograph in English devoted entirely to the music of the trouveres is long overdue, particularly when considering that many of the new perspectives on genre, voice, orality, gender, sexuality, and performance in Old French lyric poetry have come from scholars of literature. O'Neill's study may not satisfy all expectations-at 226 pages including bibliography and indices, it is a slim volume for such a vast subject-but the analyses in Courtly Love Songs offer many insights into the structures and forms of trouvere song and provide ample material for further reflection. In the chapter entitled "The grand chant of the Trouveres: An Introduction," O'Neill surveys the genre characteristics of trouvere song using a representative example by Gace Brule (a trouvere active at several French courts in the decades around 1200): "N'est pas a soi qui aime coral­ ment:' In "The Manuscript Tradition: Sources and Notation;' O'Neill divides the manuscripts into two chronological phases based on a taxonomy of their notation, while acknowledging that the "phase two sources do not form a single cohesive group" (38)-the periodization being necessarily loose because the individual manuscripts are difficult to date with precision (29). For the most part, O'Neill's classification does not take into account the later additions to the manuscripts, although she does address questions of rhythmic interpretation that are raised by the use of mensural notation in the additions to the "Chansonnier du Roi" (Paris, Bibliotheque Nationale de France, fonds franyais 844). These additions also bear witness to intriguing developments in musical form and genre, and it would have been pertinent Current Musicology, No. 83 (Spring 2007) © 2007 by the Trustees of Columbia University in the City of New York 183 184 Current Musicology for O'Neill to acknowledge the treatment of this repertoire in Judith Peraino's (1995) dissertation. O'Neill's typology of notational forms, as well as her account of orality and literacy in the music of Adam de la Halle, confirms some conclusions in Dorothy Keyser's (1993) study of Paris, Bibliotheque Nationale de France, fonds fran
