Exposition can be seen in music, films, television shows, plays, and written text. It is the writer's opportunity to give background information to the reader or listener about the setting, establish the theme and introduce the characters.
Exposition in written texts also gives background and character information; but, it can be more difficult to understand as a literary tool than exposition in music, plays or other visual entertainment since there are so many ways to present the information in written text.
The word "exposition" comes from the Latin and means "to place." It informs, describes, and explains. Regardless of the type of exposition you write, the writing needs to be concise and easy to understand.
There are several types of exposition:
Example: The U.S. flag consists of thirteen alternating stripes of red and blue, representing the 13 original states. In the top left of the flag there is a field of blue with fifty stars, one for each state.
Example: The alligator has a u-shaped, round snout and tends to live in freshwater swamps and streams. The crocodile has a long, v-shaped nose and can live in saltier waters as well as freshwater habitats.
Example: The Civil War was caused because of conflicts between states on the subjects of states' rights and slavery. Before the war the southern states relied on slaves to plant and harvest the crops. These southern states wanted to make decisions separate from the northern states and banded together as "The Confederates," threatening to leave the U.S. The northern soldiers were victories in the Civil War, reestablishing that states in the south had to confirm to U.S. laws, including the abolishment of slavery.
Example: This family was a victim of a problem they could have avoided-a problem that, according to Florida park rangers, hundreds of visitors suffer each year. "Several times a month," ranger Rod Torres of O'Leno State Park said, "people get scared and leave the park in the middle of the night." Those people picked the wrong kind of park to visit. Not that there was anything wrong with the park: The hikers camped next to them loved the wild isolation of it. But it just wasn't the kind of place the couple from New Jersey had in mind when they decided to camp out on this trip through Florida. If they had known about the different kinds of parks in Florida, they might have stayed in a place they loved."
Example: The timeline of the Civil War included these key timeframes:
1600s - States begin to adopt laws regarding slavery that are appropriate for their individual states.
1700s - Some states are beginning to express thoughts that slavery should be abolished.
1800s - Rebellion starts against slavery with seven states threatening to secede from the U.S. Lincoln was inaugurated. The Civil War began which the north eventually won.
Exposition gives the reader or listener the full spectrum of the story. By adding more details the writer can open the door and let the reader fully step into the story or the music.
