Flow Studies for Euphonium, 2nd ed.; Vining/Benton

Appropriate for high school through professional euphonium players, Flow Studies is designed to help you develop air flow efficiency by playing musical phrases in a wide array of ranges, keys, and rhythms. The etudes are presented in a daily format with eight etudes per day, for a total of fifty-six etudes. Flow Studies offers a musical way to cultivate the important technical skill of breath control, and musical incentives are always more compelling to musicians than technical ones!
