In the past, I've read the Elements of Style, Style: Ten Lessons in Clarity and Grace, and Steven Pinker's Sense of Style. The first two advice the utmost brevity, the Elements of Style giving it greater precedence than rhythm. Sense of Style is more lenient but offers no rule for how much wordiness is too much.
There are some writers, early and modern, who seem to have refused to follow a style guide, because, although their prose tends to obey certain constraints, no rules can be derived from their stylistic tendencies. It seems that, rather than following a style guide, other considerations took their attention, such as rhythm.
The necessity of rhythm seems to demand a breach of most style guides, which I've heard that editors obey faithfully, and which are considered handbooks of good style. But without a good style guide, some writers tend to introduce great verbosity into a piece of writing, and great unclarity, as they deem unlimited their freedom to deviate from the rules.
So my question is: Is there a better style guide, not demanding the utmost faithfulness to its guidelines, but giving additional guidelines on how to properly deviate from the rules given by other style guides?
