Country music originated in the southern United States in the 1920s, blending styles of American folk music, Irish and Celtic fiddle tunes, and European immigrant music. Some key early artists included Jimmie Rodgers, known for yodeling, and Johnny Cash. While the genre has evolved over time, common instruments include guitar, fiddle, and steel guitar. Country music videos have become more stereotypical over time, now often featuring the country lifestyle through locations, clothing, and vehicles.
