Etudes have been composed to address the primary challenges found in ten selected euphonium wind band pieces. Each work was chosen based on its frequency of occurrence in military band auditions as well as its appearance in excerpt books and journal articles. Practice drills, practice variations, and overtraining studies are the primary concepts used for composing each etude. List of selected works: (1) Roman Carnival Overture Op. 9, Hector Berlioz; (2) First Suite in E-flat for Military Band Op. 28 No. 1, Gustav Holst; (3) Barnum and Bailey's Favorite, Karl King; (4) The Melody Shop, Karl King; (5) Aegean Festival Overture, Andreas Makris arr.
