In B-flat major, in ternary form.

• A (measures 1-8)
• B (measures 9-16)
• A (measures 17-24)
• Coda (measures 25-31)

In the opening theme, the same tonic chord is sustained for three measures, creating a relaxed harmonic rhythm and a broad, expansive atmosphere. Although the left-hand accompaniment consists of eighth-note triplets, its high register suggests a need for a soft and light touch, considering the piano's timbre. Supporting this, the dynamic marking is piano, with the instruction dolce (sweetly/lovingly). Section B transitions from descending sequences in two-measure units to ascending sequences in one-measure units. From measure 21, the use of secondary dominant chords leads to a beautiful harmonic development, eventually concluding gently with perdendosi.
