The United States, a capitalist country powerful in politics, economy, military and culture, goes ahead in many aspects. Yet in view of the nourishment and development of folk music, America falls behind due to the particular characteristics of the American people. In its history of over 200 years, country music has been outstanding, for it embraces the essence of the 20th-century America. From the very beginning up till now, country music has always reflected the themes and styles of the times. Country music is a huge mirror of American culture, and every branch of it is closely related to the cultural characteristics of the time. Simple and plain though the lyrics are, they contain profound significance and summarize the basic life values of American farmers and peasants, and even most American people. The audience of country music has expanded from the peasants in hills and pioneers to the majority of Americans and then to people around the world. Whatever the branch, country music occupies an irreplaceable position in today’s music world. With the passage of time and historical changes, country music has always been reflecting people’s thought and living style. As a significant form and carrier of human art, country music contains rich cultural and historical connotations.
