Love Hemingway. Straightforward description--of intense and near-universal underlying human experience. To me, the emotional punch of Hemingway comes from the second of these attributes, not the first.
I've been plumping for
The Emotional Craft of Fiction endlessly lately, and recently got to exercise #25: Emotional language. Maass compares words to gems and sentences to necklaces. One can appreciate a gem of a word for it's rarity, it's clarity, its brilliance. But the beauty of a necklace--with lines, and balance, and flourishes--is a step beyond a gem.
I think conceptualizing sentences as necklaces is pertinent here, because there are so many different kinds of beautiful necklaces. Some are simple gold linked chain, fine against the neckline, a mere hint of elegance. Others are dazzling assortments of diamonds and emeralds evocative of wealth and power, and others are beautiful for their cultural meaning and implications, and so on and so forth.
Different people are drawn to different styles at different times and for different purposes. Maass recommends introducing linguistic flourishes into one's sentences as a means of 'crafting necklaces,' and these recommendations include but are not limited to the use of: repetitions, parallels, reversals, symmetry and contrast. He also says "Or, heck, just make your prose sound good." (page 157.)
"Strong words strung in a shapely pattern." He quotes one of Churchill's speeches:
We have before us an ordeal of the most grievous kind. We have before us many, many long months of struggle and of suffering. You ask, what is our policy? I can say: It is to wage war, by sea, land and air, with all our might and with all the strength that God can give us; to wage war against a monstrous tyranny, never surpassed in the dark, lamentable catalogue of human crime. That is our policy. You ask, what is our aim? I can answer in one word: It is victory, victory at all costs, victory in spite of all terror, victory, however long and hard the road may be; for without victory, there is no survival.
OP: A suggestion for you to take or leave: "Emotional language," exercise #25 in Maass's
