A、the use of good-patterned sentence structures B、meaning effect rather than the pattern of a sentence C、the flow of sound which

Music and literature, the two temporal arts, contrive their pattern of sound in time; or, in other words, of sounds and pauses. Communication may be made in broken words, the business of life be carried on with substantive alone; but that is not what we call literature; and the true business of the literary artist is to plait or weave his meaning, involving it around itself; so that each sentence, by successive phrases, shall first come into a kind of knot, and then, after a moment of suspended meaning, solve and clear itself. In every properly constructed sentence there should be observed this knot or hitch; so that we are led to foresee, to expect, and to welcome the successive phrase. The pleasure may be heightened by an element of surprise, as, very grossly, in the common figure of the antithesis, or with much greater subtlety, where an antithesis is first suggested and then deftly evaded.Each phrase, besides, is to be comely in itself; and between the implication and the evolution of the sentence there should be a satisfying equipoise of sound; for nothing more often disappoints the ear than a sentence solemnly and sonorously prepared, and hastily and weakly finished.Nor should the balance be too striking and exact, for the one rule is to be infinitely various; to interest, to disappoint, to surprise, and yet still to gratify; to be ever changing, as it were, the stitch, and yet still to give the effect of an ingenious neatness.
