There is typically more than one way to communicate an idea with regard to sentence structure, and how the sentence is structured contributes to its tone. For instance, short/brief sentences can contribute to a sense of hurry or haste. For instance let’s look at the following sentences:
I was late. I quickly ate. I brushed my teeth. I forgot to comb my hair. Then, I was out the door.
Can you feel the tone of urgency communicated by the short sentences?
Likewise, long and drawn out sentences can provide the tone of sluggishness and/or unwillingness. This is something to keep in mind when constructing your own sentences—as you are writing always be aware of your sentence structure and the tone it may communicating.
