Unique musical forms, such as jazz, rock and roll, Chicano music, and the blues, grow in the US by mixing a variety of culturally distinct musical traditions to create a new form.

At the executive (行政的) level, the country is headed by a mixedrace president; two posts(职位) on the Supreme Court are held by members of the country's two largest minorities.There is also diversity in state and local governments.
