Writing for the ear and writing for the eye are not the same thing. Writing for the ear includes storytelling, lectures, power-point presentations, podcasts, speeches, and commercials. You have to pay close attention to how the piece might sound when read aloud and consider how people might react when listening to it.
There are some tricks to writing for the ear, instead of the eye. They include using short words, because multi-syllabic words are not as good as their simpler counterparts. Big words are impressive to read but not as nice to hear. Use short sentences; they are more impactful than long sentences. Sentences with less than 20 words are more memorable and capturing than words that exceed 20 words. Using everyday words is better for the ear. English speakers tend to use the same words on a daily basis and if those are used in this writing then the writing will be accepted. Using contractions is very important. During a conversation we say “don’t” and “should’ve” because they work better for ear than “do not” or “should have.” Contractions roll off the tongue. The number one thing that always needs to be done when writing for the ear is speak the writing aloud. That’s when you’ll figure out what sounds good and what doesn’t.
