Sonata-rondo form. The melody of the tranquil rondo theme, similar to the preceding two movements, features the piano solo presenting the antecedent phrase, with wind instruments responding. However, the piano does not always maintain dominance; in the episodes, wind instruments take the lead as the melodic voice. In the second episode, which functions as a development section, motives from the rondo theme melody are insistently presented in a minor key, creating a tense atmosphere. The harmonic device of departing to keys other than the tonic in the coda is a technique shared with the first movement.
