Inspired by William Butler Yeats' poem of the same name, the piece depicts the images described by Yeats' poetic narrative through a double theme and variations form consisting of two contrasting themes that are related, one ascending and one descending. Each theme represents one of the two contrasting sections of the poem and is followed by a set of five variations for a total of ten. Since the rhyme scheme of each section of the poem is divided into five phrases of four lines, each musical variation corresponds to four lines of text.en-USYeats, W. B. (William Butler), 1865-1939.
