The poem uses an irregular rhyme scheme, often using couplets or ABAB rhymes, but also repeating some rhymes many times in succession, or allowing long gaps between a word and its partner. The metre is also irregular, typically (though not always) keeping three or four stresses, in varying feet, per line. The lines below show the varied stress patterns, as well as an interior rhyme (grey/decay) picked up by the end-rhyme with "away". The initial line quoted here, "bright", rhymes with "night" a full seven lines earlier.
