The impetus for writing 39 Etudes began as a desire to provide the player with study materials designed to attack specific problems. The euphonium has a significantly shorter air column than a tuba, which lends the player more deftness and agility. The player should strive to play with equal facility, clarity, accuracy, smoothness of slurs, and purity of intonation as all the other higher brass instruments.
39 Etudes employs different modes, keys, and scales, along with shifting tonalities. It is imperative that the player listen carefully to every interval in order to keep the intonation pure and the pitch accurate.
