This etude is designed for solid intermediate and advanced students to strengthen the inner thumb and index fingers of each hand. Until the final few measures, no pedal is to be used. In order to keep the piece smooth, the performer must move with extreme swiftness and with total confidence as there are many wide-leaping intervals. Additionally, it is important to alter neither the dynamic level nor the tempo until the ritard. Once mastered, this piece makes a wonderful, if slightly creepy, encore solo.
