Terms such as "blank verse", "free verse" and "heroic couplet" are used to refer to poems with particular forms. I am curious to know whether there exists a term for poems that are strongly structured by means of repetitive poetical devices such as anaphora, epistrophes and parallelisms. A good example is Tolkien's "Ring Verse":
Three Rings for the Elven-kings under the sky,
Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.
Another example comes from the lyrics of the song "Last Quest" by the band Kerion:
Far away beyond the hills
Far away over the rivers
Far away this magical journey
Ride with me under the moonlight
Ride with me across the trees
Ride with me in green valleys where the sun shows all its light
