A-flat major, 3/4 time. The opening melody should be played with a sense of movement, imagining the dance of a 3/4 waltz. Avoid overemphasizing the accent on the first beat; instead, express it with a feeling of moving forward. From measure 33, the key changes to C minor. Skillfully use the left-hand staccato and right-hand triplets to express the touch and agility of the sound, changing the atmosphere. From measure 65, the melody returns in A-flat major. From measure 81, "Quasi scherzando, ma un poco piu lento," the key modulates to E major. Ensure the left-hand staccato does not become an isolated movement; instead, play it while valuing the horizontal flow. The "gran espressione" from measure 98 should be sung with greater expressiveness and passion. From measure 119, the melody from measure 33 reappears, and from measure 131, it returns to the opening. The piece concludes with an ascending passage, culminating in a brilliant finish on the I chord in A-flat major.
