Feel the rocking rhythm, like a cradle. Although it is in 4/4 time, it is suggested to feel it broadly, like 2/2 time (alla breve), to better express the swaying motion. Since it is written in a contrapuntal style, ensure the left hand is not passive but sings fully, and cherish the dialogue between the left and right hands. In the right hand of measures 5, 6, 15, and 16, the small hairpin crescendos and decrescendos written over single notes are practically impossible on the piano. However, imagine vocal, string, or wind instruments, and feel the amplification and decay of energy within each single note. From measure 9, the four-measure phrasing expands with the addition of two measures, reaching f (forte). From measure 15, the motif from measure 5 is played a perfect fourth higher, increasing the tension, but there is an impression of gradual purification and softening towards the resolution in measure 19. Regarding this piece, the composer has given the instruction: "Beautiful legato, transparent sound."
