jazz

A form of American music that grew out of African-Americans' musical traditions at the beginning of the twentieth century. Jazz is generally considered a major contribution of the United States to the world of music. It quickly became a form of dance music, incorporating a “big beat” and solos by individual musicians. For many years, all jazz was improvised and taught orally, and even today jazz solos are often improvised. Over the years, the small groups of the original jazz players evolved into the “Big Bands” (led, for example, by Duke Ellington , Count Basie , and Glenn Miller ), and finally into concert ensembles. Other famous jazz musicians include Louis Armstrong , Benny Goodman , and Ella Fitzgerald .
