The main key is C major. It is in ternary form.

Structure

• A Section (Exposition): [a (measures 1-4) + a1 (measures 5-8)]
• B Section (Development): [b (measures 9-12) + b1 (measures 13-16) + Transition (measures 16-20)]
• A1 Section (Recapitulation): [a (measures 21-24) + a1 (measures 25-28)]
• Coda: (measures 30-34)

The theme is composed of a rhythmic arpeggiated motif and a smooth stepwise motif. Although there is no second theme, the contrasting expression of these two different motifs evokes the contrast between the first and second themes in sonata form.

In the development section, the key modulates to G major. The left hand in measures 13-14 imitates the right-hand melody from measures 9-10, creating a polyphonic texture.

In the recapitulation, the exposition is largely reproduced as is, though minor changes such as the addition of appoggiaturas can be observed. Measure 24 lacks a slur due to this change, but the phrase movement remains the same; therefore, the three quarter notes (La-Sol-Fa) should be played as an anacrusis to the next phrase, similar to measure 4.
