Using sensory details makes writing more vivid so that readers can see, hear, feel, taste, and smell what’s happening in a story.
Naturally, it’s a little more complicated than that.
First of all, we have more than five senses. Vestibular sense involves movement and balance. Proprioception is also called body awareness and tells us where our body parts are in relation to each other and how to do things, like pick up a heavy rock or delicate egg. Chronoception lets us sense the passage of time. We can also sense temperature and pain.
This article at John Hopkins University Press says there are nine senses.
An article at the University of Utah Genetics Science Learning Center says there are twenty, but it counts some senses in other animals. That might be useful if we’re writing about non-humans.
The things that we sense are interpreted through our thoughts and emotions, too.
As writers, how do we use these senses in a story? The correct answer to this and many other questions is: It depends. What’s the story you want to tell? What matters to the characters in it? What is the pace you want? Romance novels tend to be lush, and a mystery might be spare, and in either case, the senses that you evoke will guide the attention of the reader to what matters. An intriguing whiff of perfume at a party with contrasting notes of candy-like violets and earthy sandalwood might signal the start of an affair. A barking dog might make Sherlock Holmes deduce.
When we write, it’s best to go directly to the sensation. A bad example: Becky smelled acrid smoke and knew it would be toxic. Instead, this: The smoke reeked of acrid toxins. The reader will know that Becky was smelling it and recognized the smell. Fewer words are always better than more words, too.
Next, why do these particular sensory details matter? An article by Donald Maass, “
Moving Along” at Writer Unboxed, shows how to use sensory details to evoke emotion. I’m going to disagree with him, though. He says the final example is “focusing not on visualizing, sensory details,” but I say it is. Count the colors mentioned. Note the things we could taste and feel, especially the dryness. Consider the snippets of conversation we hear. It gives us the full picture with plenty of vivid sensory details in an unselfconscious way by showing us how these things matter.
