It is difficult to have a single picture of the arts and culture of this nation for its population alone is composed of different ethnic races, some of which have migrated from other countries around the globe.

It helps to know that each group of states have their own sets of cultures, which are separated from one another as each state has a different culture to another, as well. Try browsing in part, that Eastcoast, Westcoast, North America, South America and Central America. You can also sort through the art and culture of using these manners division: American north-east, north-west of America, the American Plains and Midwest, the American southeast and the American Southwest.
