The stanzas (line groupings) are quatrains (four lines to each stanza); this form allows the poet to bring the reader along the "road" to "the fine land, the west land, the land where I belong." The rhyme scheme is couplets (aabb), a soothing, childlike cadence. By contrast, the rhythm is uneven; that is, the feet vary, from iambs ("the land where I belong" -- three iambics) to trochees ("apple orchards blossom"-- three trochees) with occasional anapests and dactylics. This rambling form is appropriate to the poem's theme (an exhaustive, hectic life seeking the refuge and rest that "the west wind" promises); it wears the reader out and duplicates the fatigue that the westward wind seeks to comfort. There are subtle internal rhymes and repititions ("brother," for example) and a complex interweaving of natural sounds and images (birds, for example) that give the poem a remarkable complexity.
