Country music (often called “country & western”) is a distinctly American popular‑music genre that emerged in rural Southern and Southwestern United States in the early 20th century. It’s defined by its straightforward song structures—typically simple I–IV–V chord progressions in 4/4 time—story‑driven lyrics about everyday working‑class life, and a characteristic Southern vocal twang. Instrumentation centers on acoustic and electric guitars (including steel guitar), banjo, fiddle, harmonica, and upright bass, with drums added in more modern recordings. Early country fused Appalachian folk ballads, Celtic traditions, African‑American blues, and gospel; key substyles include honky‑tonk, Western swing, bluegrass, and contemporary country‑pop. Whether heartfelt ballad or upbeat dance tune, country songs prioritize relatable narratives, plainspoken honesty, and melodic simplicity—a formula that has made country one of America’s most enduring and widely enjoyed musical forms.
