English composer Frank Bridge (1879-1941) is well known as Benjamin Britten's teacher and to a lesser degree for his chamber music. Because his mature creative period occurred between the First and Second World War, his works were not well studied or performed until the 1970s, well after his death. This dissertation discusses Bridge's life and his music, how World War I affected in this work, and specifically the work Oration Concerto Elagiaco. Oration is considered historically in terms of its meaning and delayed premiere. Additionally, the work's fantasy arch form, Bridge's signature compositional style, and the character of each section is discussed. Finally, this dissertation provides a practical guide to the work, providing practice and performance suggestions for the numerous complex and technically challenging portions of the concerto.

Gyorgy Druschetzky was a noted Czech composer of Harmoniemusik, who wrote more than 150 partitas and serenades, along with at least thirty-two other selections for larger wind groups. This is in addition to twenty-seven symphonies, eleven concertos (most for wind instruments), two fantasias, forty-seven string quartets, two operas, a ballet that is lost, and other miscellaneous chamber music for various combinations of wind/string instruments. Three of his works for winds have existed only in manuscript form since their composition: Concerto in E-flat pour 2 clarinett en B, 2 cors en E-flat, 2 fagott; Overture to Mozart's Die Zauberflöte; and Partitta a la camera a corno di bassetto primo, secondo, terzo, due corno di caccia, due fagotti. These works remain remarkably interesting to modern ears and deserve to be heard in the twenty-first century. Along with a brief examination of Druschetzky's life and how it figures into the history of Harmoniemusik, this work presents each piece edited into a modern performance edition.
