Gluck's poetry is known for its directness, simplicity, and often lack of traditional poetic devices. This poem exemplifies that style. It's written in free verse, which means it doesn't follow a set rhyme scheme or metrical pattern. This allows the poem to flow naturally and emphasizes the emotional content.
While there might be some internal rhyme or assonance within the poem, it's not structured around a consistent rhyme scheme like a sonnet or a ballad.
