This is a brilliant concert etude. It demands the performer's musical concentration and technique, including intricate right-hand passages, changes in left-hand rhythm, and inner voice movements, but by mastering these, one can surrender to the flow and groove of the music and enjoy the piece.

The section that develops from the delicate opening motif, rapidly ascending in measure 4, evokes Chopin's "Minute Waltz" and provides exhilarating momentum. By playing through with a crescendo but without rushing, a refreshing impression can be created. From measure 9, the accented notes in the right hand align with the left-hand rhythm. Syncopation creates rhythmic displacement, making the music even more vibrant. This section reveals Gillock's unique sensibility, given his fondness for jazz, and incorporating a touch of playfulness into the performance will make it sound captivating. While valuing the sense of tempo, be sure to fully feel the rhythmic "groove" as you play.

The middle section shifts to E-flat major, and as indicated by "Meno mosso molto lyrico," the atmosphere changes dramatically. The melody should be sung generously and carefully, as if taking a deep breath. In passages where both hands move closely together, it is effective to play softly while listening to the sonorities, as if harmonizing. Creative use of the pedal is also required; avoid muddiness, but maintain the connection between notes.

Throughout the piece, the elegance of the waltz, the rhythmic sensibility of jazz, and the sharp technical demands of an etude coexist in a balanced manner. While carefully grasping each element during practice, it is ultimately important to enjoy the music itself during performance.
