Jazz, as a genre of music, has intrinsic values of its own. The study of American history would be imperfect without taking into account the contribution of jazz which it occupies certain shares in formation of American culture and identity. In fact, jazz was exclusively a noble product through which African-American could access to the mainstream culture and made a distinct image of America per se in 21st century global world. However, the evolution of jazz music cannot be seen as a consequence of one moment event but associates with long and persistent struggle which develops its concrete shape over time and became a widely diffused music. This paper attempts to define the connotation ‘Jazz’ as more than musical term, perhaps its historical meanings are extended to other domains mostly in culture, in American history. In other words, jazz musicians were revolutionizing not only music but also the concept of culture. However, the main source of such impacts is still to be rooted in jazz as musical culture that itself changes from the parochial model of Euro-centric concept of music.
