Assonance is the strategic repetition of vowel sounds in close proximity to each other and is frequently used to create internal rhyming.
A Chance of Rain in the Afternoon
Throughout the day, relaxed fingers of cloud waved from a brittle brightness of sky until, at 3:00, out of the sameness of the day before and before and before, a wind swirled up and through and long, and drought-weary leaves, no will to cling, fell to fleck the yellow lawn. As a false darkness stretched below a canopy of clouds, the insistent wind caused thunderheads to collide, littering the sky with rolling-train sounds, sending skinny, witch-fingers of lightening through the clouds. The showy commotion roused no rain: the crooked, yellow fingers fled the sky; the train of thunder passed on by; and our hopeless rain-hopes waned, along with the lightening, the wind, and the thunder din.
