If you are asking about a specific poem, you need to submit another question and give the title of the piece you are analyzing.
In general, many readers of poetry find a sense of movement in the poems they read is imparted by the combined use of rhythm and rhyme. Rhythm refers to the pattern of accented and unaccented syllables frequently used in poetry and most obvious when the poems are read aloud. Different combinations are used by authors to create the effect they are attempting to convey. The boldface syllables are the accented ones in this "poem."
Twin-kle twin-kle lit-tle star!
How I won-der what you are.
Rhyme contributes to movement by connecting the lines of a poem. The reader feels anticipation as s/he recognizes the pattern being created by the repetition of certain combinations of letters and sounds. In the poem "Stopping by Woods on a Snowy Evening" by Robert Frost, the 1st, 2nd and 4th line of each stanza rhyme. The 3rd line of each stanza rhymes with the 1st, 2nd, and 4th line of the next stanza.
Whose woods these are I think I know.
His house is in the village though;
He will not see me stopping here
To watch his woods fill up with snow.
My little horse must think it queer
To stop without a farmhouse near
Between the woods and frozen lake
The darkest evening of the year.
He gives his harness bells a shake
To ask if there is some mistake.
The only other sound's the sweep
Of easy wind and downy flake.
The woods are lovely, dark and deep.
But I have promises to keep,
And miles to go before I sleep,
And miles to go before I sleep.
