Country music is a popular American musical style that began in the rural Southern United States in the 1920s. It takes its roots from Western cowboy and southeastern American folk music. Country music often consists of ballads and dance tunes with generally simple forms and harmonies accompanied by mostly string instruments such as banjoes, electric and acoustic guitars, fiddles, and harmonicas.

The term country music gained popularity in the 1940s in preference to the earlier term hillbilly music. The term country music is used today to describe many styles and subgenres. In 2009 Country music was the most listened to rush hour radio genre during the evening commute, and second most popular in the morning commute.

Immigrants to the Maritime Provinces and Southern Appalachian Mountains of North America brought the music and instruments of the Old World along with them for nearly 300 years. They brought some of their most important valuables with them, and to most of them this was an instrument: “Early Scottish settlers enjoyed the fiddle because it could be played to sound sad and mournful or bright and bouncy” The fiddle, the German derived dulcimer, the Italian mandolin, the Spanish guitar, and the West African banjo were the most common musical instruments. The interactions among musicians from different ethnic groups produced music unique to this region of North America. Appalachian string bands of the early 20th century primarily consisted of the fiddle, guitar, and banjo. This early country music along with early recorded country music is often referred to as old-time music.
