the final movement of the concerto is a seven-part rondo form (abacaba). the solo piano introduces the main theme before the full orchestra affirms the soloist's statement. the rondo's b-section begins with piano scales, before the orchestra again responds. the c-section is much longer, presenting the theme from the a-section in three different keys before the piano performs a passage of arpeggios. rather than finishing with a strong entrance from the orchestra, however, the trill ending the cadenza dies away until the introductory theme reappears, played first by the piano and then the orchestra. in the last section, the theme undergoes variation before the concerto ends with a short cadenza and robust orchestral response.
