Robert Louis Stevenson said this quote

“ We may now briefly enumerate the elements of style.  We have, peculiar to the prose writer, the task of keeping his phrases large, rhythmical, and pleasing to the ear, without ever allowing them to fall into the strictly metrical: peculiar to the versifier, the task of combining and contrasting his double, treble, and quadruple pattern, feet and groups, logic and metre—harmonious in diversity: common to both, the task of artfully combining the prime elements of language into phrases that shall be musical in the mouth; the task of weaving their argument into a texture of committed phrases and of rounded periods—but this particularly binding in the case of prose: and, again common to both, the task of choosing apt, explicit, and communicative words.  We begin to see now what an intricate affair is any perfect passage; how many faculties, whether of taste or pure reason, must be held upon the stretch to make it; and why, when it is made, it should afford us so complete a pleasure.  From the arrangement of according letters, which is altogether arabesque and sensual, up to the architecture of the elegant and pregnant sentence, which is a vigorous act of the pure intellect, there is scarce a faculty in man but has been exercised.  We need not wonder, then, if perfect sentences are rare, and perfect pages rarer.-ON SOME TECHNICAL ELEMENTS OF STYLE IN LITERATURE ”
