Stanzas do not have to repeat but sometimes they do depending on the author. Repetition has been one of the bases for many poetic forms. This can heighten the emotional impact of a piece. <span> A sound, syllable, word, phrase, line, stanza, or metrical pattern can be repeated. Hope this answers your question.</span>
