From the emergence of plainsong to the end of the fourteenth century, this Companion covers all the key aspects of medieval music. Divided into three main sections, the book first of all discusses repertory, styles and techniques - the key areas of traditional music histories; next taking a topographical view of the subject - from Italy, German-speaking lands, and the Iberian Peninsula; and concludes with chapters on such issues as liturgy, vernacular poetry and reception. Rather than presenting merely a chronological view of the history of medieval music, the volume instead focuses on technical and cultural aspects of the subject. Over nineteen informative chapters, fifteen world-leading scholars give a perspective on the music of the Middle Ages that will serve as a point of orientation for the informed listener and reader, and is a must-have guide for anyone with an interest in listening to and understanding medieval music.
