Poetry can follow a strict structure, or none at all, but many different types of poems use poetic devices. Poetic devices are tools that a poet can use to create rhythm, enhance a poem's meaning, or intensify a mood or feeling. These devices help piece the poem together, much like a hammer and nails join planks of wood together.
