Country music is one of the most popular kinds of music in the United states today because it is about simple but strong human feeling and events---love, sadness, good times, and bad times. It tells real—life stories and sound the way people really talk.
Country music, sometimes is called country-western, comes by two kinds of music. One is traditional music from the eastern United States. The other is traditional cowboy music from the west. The singers usual play guitars. At first it is popular mostly in the South. And during World War II, thousands of Southerners went to the Northeast and Midwest to work in the factories. They took their music with them. Soldiers which were from the rest of the country went to army camps in the South learned country music. Thus they became popular all over country.
