Where in the poem Eldorado is there an example of consonance?

You're asking for an example of consonance in Edgar Allan Poe's poem "Eldorado." While there are many instances of alliteration (repetition of consonant sounds at the *beginning* of words) in this poem, consonance is a bit trickier to pinpoint.

Consonance refers to the repetition of consonant sounds *within* words, not necessarily at the beginning. Here's one possible example from "Eldorado":

"Gaily the gilded procession went" (Line 3)

* The repeated "g" sound in "gaily," "gilded," and "went" could be considered consonance.

However, Poe's use of consonance is less frequent and less obvious than his use of alliteration. If you want to analyze other potential examples, consider focusing on the repeated consonant sounds within lines.
