The word [jazz] never lost its association with those New Orleans bordellos. In the 1920s I used to try to convince Fletcher Henderson that we ought to call what we were doing 'Negro music'. But it's too late for that now.
Duke EllingtonPut it this way: Jazz is a good barometer of freedom... In its beginnings, the United States of America spawned certain ideals of freedom and independence through which, eventually, jazz was evolved, and the music is so free that many people say it is the only unhampered, unhindered expression of complete freedom yet produced in this country.
