A Second Supplementary Catalog of Early Wind Band and Wind Ensemble Repertoire is the twelfth volume in Dr. David Whitwell’s ground breaking thirteen-volume History and Literature of the Wind Band and Wind Ensemble series. The repertoire found in this supplementary volume is the result of visits to specific European collections recommended by other musicians. These include a deserted palace in Hungary, a large Hautboisten collection in Sweden and a visit in Paris with the widow of Charles Koechlin. Also included in this volume are lists of original wind repertoire from the early twentieth century which, because it was created outside the world of educational publications, may not have come to the attention of most conductors. Whitwell’s meticulous scholarship reveals the continuous history of the wind ensemble, from its earliest roots to the nineteenth century - an unbroken tradition of wind music that music scholars have never been fully able to appreciate until now.
