While being mindful of the elegant flow characteristic of a Viennese Waltz, utilize the propulsive force of the anacrusis to naturally lead into the first beat. The anacrusis possesses the energy to create musical flow. On the first beat, it is important to listen carefully to the sound of the chords created by both hands and perceive their individual differences. There are various types of chords on the first beat; by isolating and playing these sections, the coherence of the phrase will naturally become apparent.

For example, in the phrase from measures 1-4, the chords on the first beat gradually descend, creating a sense of closure. Control the sound so that the entire phrase naturally converges. In the subsequent measures 5-8, the bass descends on the chord in measure 6, increasing the depth of the sound. Here, it is crucial to be mindful of the bass support, perceive the dominant-tonic relationship, and carefully craft the changes in sound.

From measure 9, following the anacrusis's melodic opening, a light, staccato accompaniment is added. It is important to begin p, suppressing the volume while feeling the anticipation of moving towards f, and recognizing this as the source of the phrase. The "Sol-La-Si-Re" at the culmination of the crescendo should be played energetically, with an increased sense of propulsion. As the right hand's movement quickens, take ample time on the second beat of measure 13 with the left hand, giving it weight to provide stability to the music. Such agogic adjustments will likely be necessary throughout this piece.

Pay attention to the difference between sections where a hairpin crescendo is written on the eighth-note anacrusis and where it is not. In sections where it is written, aim for a more dynamic expression, mindful of the increase in energy.

At "poco allargando" in measure 27, adjust the tempo as if applying a slight brake, preparing for the next four measures. The key here is to maintain a natural flow, avoiding an abrupt slowdown in this section.

Then, from measure 33, in the "vivace" section, strive for a brilliant, dashing performance, utilizing the lightness of your fingertips. Since the chords have a flat-key sonority, cherish the softness of the tone and imbue the lightness with an elegant expression.

The final arpeggio in measure 37 is a C major I chord; be mindful of a sound that conveys both brilliance and a sense of security and stability. For the final chord, direct your awareness to the tanden (lower abdomen) and conclude with dignity.

Express the unique elegance and lightness characteristic of a Viennese Waltz, aiming for a brilliant and wonderful performance.
