To write lyrical prose, one must use wording that conforms to a lyrical voice. When the wording is altered, the cadence is altered as well. Some cadences fit one voice, while other cadences fit other voices. To certain cadences, wording must conform to establish a certain voice. Control over syntax helps to accomplish this.
But of all the syntactic patterns available, not all produce the right cadences. This is because the word-choice disallows it. I find that in this case, although for the task, the use of a Thesaurus is often recommended, it appears in my mind to be not always helpful, as it lacks an adequate supply of synonyms.
My questions then are, “Seeing there is a lack of synonyms, and seeing that cadence cannot be made by syntax with sufficiency, how does one create their desired voice?", "Is it done through a creative use of words, despite the lack of synonyms?", and, "Does this lessen the brevity which is possible in a piece?".
