Here's why:
* Focus on personal feelings and emotions: The poem explores the speaker's contemplation of choice and its potential impact on life.
* Musicality and rhythm: Frost's use of rhyme and meter creates a musical quality, adding to the poem's evocative nature.
* Concise and evocative language: The poem is relatively short and uses vivid imagery to create a lasting impression on the reader.
While "The Road Not Taken" could be considered a narrative poem because it tells a story, the focus on the speaker's internal thoughts and feelings makes it primarily a lyric poem.
It's also worth noting that some critics categorize it as a philosophical poem due to its exploration of themes related to choice, destiny, and the meaning of life.
