Jazz is a genre of music that originated in the late nineteenth and early twentieth century. Jazz emerged in many parts of the United States of independent popular musical styles; linked by the common bonds of European American and African American musical parentage with a performance orientation. Jazz makes heavy use of improvisation, polyrhythms, syncopation, and the swung note, as well as aspects of European harmony, American popular music, the brass band tradition, and African musical elements such as blue notes and ragtime. A musical group that plays jazz is called a jazz band.
As jazz spread around the world, it drew on different national, regional, and local musical cultures, giving rise to many distinctive styles: New Orleans jazz dating from the early 1910s, big band swing, Kansas City jazz and Gypsy jazz from the 1930s and 1940s, bebop from the mid-1940s, Afro-Cuban jazz, West Coast jazz, ska jazz, cool jazz, Indo jazz, avant-garde jazz, soul jazz, modal jazz, chamber jazz, free jazz, Latin jazz, smooth jazz, jazz fusion and jazz rock, jazz funk, loft jazz, punk jazz, acid jazz, ethno jazz, jazz rap, M-Base and nu jazz.
Louis Armstrong, one of the most famous musicians in jazz, said to Bing Crosby on the latter's radio show, "Ah, swing, well, we used to call it syncopation, then they called it ragtime, then blues, then jazz. Now, it's swing."
In a 1988 interview, jazz musician J. J. Johnson said, "Jazz is restless. It won't stay put and it never will". (Full article...)
