Is there any examples of euphony in "The Road Not Taken" by Robert Frost?
"Euphony" is just something that is pleasing to the ear. The rhyme and rhythm in this poem are both lovely.
Euphony can use alliteration, assonance, rhyme, or just certain combinations of letters that sound nice. It doesn't have a very strict definition. See this page for more information.
I think the ABAAB rhyme scheme as well as the meter (iambic tetrameter, because of the four) make the poem pleasing to hear.
Incidentally, I also love this poem because the paths have been taken equally in the past, yet people seem to think that the narrator took the less chosen one. Also, we don't know if the narrator thinks they made the right decision!
