What is poetic rhythm?

From ancient times to modern times, many changes have taken place in poetry. The so-called rhythm, the most fundamental purpose is to facilitate the poet to catch his breath ... not to feel suffocated after reading a paragraph. It and rhythm are two different concepts, rhythm is within the scope of metrical consideration, and the requirements of modern poetry in metrical aspects are far lower than those of ancient poetry. For example, the Cambridge you mentioned has a little consideration in rhythm, but it has not been done in meter. In addition, rhythm also has a far-reaching impact on the meaning of poetry. At the station, "silence is better than sound". Everyone has his own rhythm when reading every poem. When a poet writes, he only follows his own rhythm. You can change some long poems you sang before, and then it becomes a song, which may be just a poem for poets.
