In the Raven by Edger Allan Poe  rhyme scheme  is the device that plays a larger role .he uses through out the whole poem. It plays a large role because  it gives the poem a rhythm.

In the Incident In The Rose Garden by Donald Justice imagery is the device that plays a larger role .he uses it when when he says and there stood death in the garden. It plays a large role because it makes the reader picture what is going on.
