What is chapter repetition?

This sentence pattern is often used in poetry.

Repetition of chapters and sentences means that the upper and lower sentences or the upper and lower paragraphs are repeatedly sung in the same structural form, which is a means of expression. This technique has the characteristics of reciprocating expression effect, beautiful phonology, artistic conception and implicit beauty, and is often used in poetry.

There are many repeated sentences in The Book of Songs, and the words used in each chapter are basically the same. Only change the middle words and sing them repeatedly to show the progress of action or the change of mood. The extensive use of reduplicated words, disyllabic words and rhyming words enhances the vividness and musicality of language, and its functions are to deepen the theme, render the atmosphere and deepen the emotion.
