 In other cases , the choice of text has led the composer to different symphonic structures . Havergal Brian allowed the form of his Fourth Symphony , subtitled " Das Siegeslied " ( Psalm of Victory ) , to be dictated by the three @-@ part structure of his text , Psalm 68 ; the setting of Verses 13 – 18 for soprano solo and orchestra forms a quiet interlude between two wilder , highly chromatic martial ones set for massive choral and orchestral forces . Likewise , Szymanowski allowed the text by 13th @-@ century Persian poet Rumi to dictate what Dr. Jim Samson calls the " single tripartite movement " and " overall arch structure " of his Third Symphony , subtitled " Song of the Night " .
