This Companion is the first book to cover so many diverse aspects of brass instruments and in such detail. It provides an overview of the history of brass instruments, and their technical and musical development. Although the greatest part of the volume is devoted to the western art music tradition, with chapters covering topics from the medieval to the contemporary periods, there are important contributions on the ancient world, non-western music, vernacular and popular traditions and the rise of jazz. Despite the breadth of its narrative, the book is rich in detail, with an extensive glossary and bibliography. The editors are two of the most respected names in the world of brass performance and scholarship, and the list of contributors includes the names of many of the world’s most prestigious scholars and performers on brass instruments.
