Repetition in "the raven" gives the sensation of dark and dreary mood, the word<em> "nevermore"</em> is repeated at the end or nearly every stanza.
Repetition of consonant sounds is here:<em> "and the silken sad uncertain rustling of each purple curtain"</em>. This consonance let people know what Poe was thinking when he wrote the text.
Point of view is the despair of the man and the echo of his sadness throughout the whole poem.
