In the poem "April Rain Song" by Langston Hughes, lines 1 and 3 use the poetic device of repetition.
Here are the first three lines of the poem:
"Let the rain kiss you
Let the rain beat upon your head with silver liquid drops
Let the rain sing you a lullaby"
In line 1, the phrase "Let the rain" is repeated, emphasizing the action of the rain and creating a sense of invitation or permission.
In line 3, the phrase "Let the rain" is repeated once again, reinforcing the idea of allowing the rain to have an effect on the speaker.
The repetition of this phrase in both lines 1 and 3 adds rhythm, emphasis, and a lyrical quality to the poem, enhancing the sensory experience of the rain and drawing the reader into the imagery of the poem.
