Country music has its roots in Southern American folk music, traditionally characterized by the strong use of guitar and fiddle as main instruments.

This music genre has absorbed various elements and evolved over time, transforming from classic country to modern country. The early country styles, such as honky-tonk and western swing, centered around rhythmic performances and dance songs that reflected the lives of people at that time. Later, advanced forms like countrypolitan and Bakersfield sound emerged, influenced by various music genres such as pop and rock.

Country music is a very popular genre among Americans, as evidenced by its record sales. Garth Brooks is an icon in this field, having sold 137 million records in the U.S. alone, ranking first in all-time solo artist album sales.

He ranks second after The Beatles, showcasing his popularity. Additionally, artists like George Strait, Shania Twain, and Taylor Swift have also achieved remarkable records in album sales. In 2006, while the overall record market was declining, the country genre recorded 36 million sales, achieving a growth of 17.7%.

Country music developed within white culture, but the genre transcends race and borders, allowing people to choose according to their personal tastes. The question, "Is it strange for an Asian/Black/Hispanic to like country music?" is futile, as there is no reason to distinguish nationality or race in music. Just as hip-hop and soul music are loved worldwide, country music is the same.

Entering the 1950s, country music began to fuse with various genres, creating a more diverse and rich sound. During this period, styles such as country soul, country rock, and southern rock emerged, adding new colors to traditional country music. These changes allowed country music to combine with various music genres, enabling it to reach a broader audience.

From the late 1970s to the early 1980s, Willie Nelson, Kenny Rogers, and Dolly Parton led the golden age of country music, playing a significant role in establishing country as a mainstream music genre. However, in the early 1980s, the emergence of new wave (Duran Duran, Culture Club, etc.), black music (Michael Jackson, Whitney Houston, etc.), and glam metal (Bon Jovi, Guns N' Roses, etc.) along with pop music (Madonna, Cyndi Lauper, etc.) led to a decline in country music. As various genres attracted public interest, the market for country music narrowed.

In the 1990s, Garth Brooks led the revival of country music. Following his success, Billy Ray Cyrus's "Achy Breaky Heart" became a huge hit in 1992, bringing attention back to country music. Additionally, Shania Twain's "You're Still The One" gained international popularity, including in the UK, showcasing the potential of country pop. Shania Twain later established herself as a female country idol, with subsequent artists like Miranda Lambert, Dixie Chicks, and Carrie Underwood becoming icons of country music.

In Korea, it is sometimes compared to the genre with a similar background, trot, but in fact, country music can be seen as closer to the feel of Korean trot. Trot is primarily consumed by the elderly and still has limitations in its status, but just as other past music genres like folk rock are resurging, country music is also influencing a diverse range of people.
