<P> The famous Andante, in the subdominant key of F major, is in three parts . The opening section is for orchestra only and features muted strings . The first violins play with a dreamlike melody over an accompaniment consisting of second violins and violas playing repeated - note triplets and the cellos and bass playing pizzicato arpeggios . All of the main melodic material of the movement is contained in this orchestral introduction, in either F major or F minor . The second section introduces the solo piano and starts off in F major . It is not a literal repeat, though, as after the first few phrases, new material is interjected which ventures off into different keys . When familiar material returns, the music is now in the dominant keys of C minor and C major . Then it modulates to G minor, then B - flat major, then F minor, which transitions to the third section of the movement . The third section begins with the dreamlike melody again, but this time in the relative key of F major's parallel key, A-flat major . Over the course of this final section, the music makes its way back to the tonic keys of F minor and then F major and a short coda concludes the movement . </P> <P> The final rondo movement begins with the full orchestra espousing a joyous "jumping" theme . After a short cadenza, the piano joins in and further elaborates . A "call and response" style is apparent, with the piano and ensemble exchanging parts fluidly . The soloist gets scale and arpeggio figurations that enhance the themes, as well as a short cadenza that leads right back to the main theme . The main theme appears one final time, leading to an upward rush of scales that ends on a triumphant note . </P> <P> The second movement was featured in the 1967 Swedish film Elvira Madigan . As a result, the piece has become widely known as the Elvira Madigan concerto . </P> <P> Neil Diamond's 1972 song "Song Sung Blue" was based on a theme from the andante movement of the concerto . </P>
