It is true that the original phrasing of a sentence can be difficult to replicate, but it is not true that this is the only way to achieve a cadence that is pleasing to the ear. There are many ways to craft a sentence so that it has the same rhythm, even if the words are different. Additionally, rewriting a sentence can actually make it more concise and clear, which is a desirable quality in writing. So, while it is important to be aware of the rhythm of our writing, it is wrong to suggest that rewriting is pointless or that it will always result in a less than ideal outcome.
