The most prominent uses of literary devices include alliteration, repetition, enjambment, and caesurae.
Step-by-step explanation:
Alliteration is the commencement of two or more stressed syllables of a word group either with the same consonant sound or sound group (consonantal alliteration), as in from stem to stern, or with a vowel sound that may differ from syllable to syllable (vocalic alliteration), as in each to all.
Repetition is the act of repeating, or doing, or saying, or writing something again; repeated action, performance, production, or presentation.
Enjambment is the running on of the thought from one line, couplet, or stanza to the next without a syntactical break.
Caesurae is a break, especially a sense pause, usually near the middle of a verse, and mark in scansion by a double vertical line, as in know then thyself || presume not God to scan.
