American country music, also known as country and western, originated in the southern United States in the early 20th century. It blends folk, blues, and traditional ballads, often telling stories about working-class life. Characterized by simple melodies and harmonies, it typically features instruments like the guitar, banjo, fiddle, and harmonica. Over time, country music has evolved to include various subgenres, such as bluegrass, honky-tonk, and modern country pop.
