How does the poet use alliteration in the poem, Witness?

Alliteration is the repetition of initial consonant sounds in close proximity within lines and stanzas. Examples of alliteration include such groupings as “float free” (repeating the f- sound), “dust . . . drift,” and “twine a text.” The repetition of sounds underscores Waldner’s engagement with the physical elements of the world and the sound of the language attached to it. The alliterative passages turn language into music.
