Answer: The poem's rhyme scheme and meter have an effect of reflection and nostalgia. Being a coupled rhyme poem, and having a perfect meter, the poem gathers the attention of the reader and portrays the transience of life.
Explanation: Robert Frost used coupled rhymes as a scheme in “Nothing Gold Can Stay”. It is a type of poetry that effectively obtains the attention of the reader, and, due to the symmetry of the meter, it is quite easy to read. Moreover, the formality of the poem has an effect of nostalgia and reflection on how fleeting life is, using examples of nature and its course to convey it.
