As a companion to The Wind Ensemble Sourcebook and Biographical Guide, this catalog provides a comprehensive listing of wind ensemble works from 1650 to the present. These two volumes will be completed with a third, The Wind Ensemble Thematic Catalog 1700-1900. Representing more than 20 years of research through libraries, monasteries, and castles, the authors used primary sources when possible rather than relying on secondary sources. The authors collected a vast array of information from public and private international collections. This catalog is an exhaustive guide to international wind ensemble collections. The authors have been careful to match up various versions of the same work, and, for the first time, arrangements—an important and large part of the repertoire—are dealt with in a systematic fashion. Unique in its extensive documentation and reliance on primary sources, The Wind Ensemble Catalog is an important research tool for scholars and musicians.
