Jazz consistently evolved throughout the 20th century with numerous phases, from a New Orleans style or swing, to "free jazz," for example, which emerged in the late 1950s. Therefore, jazz itself has no precise definition, however it has rarely been a completely composed music. ]]></dc:description></metadata>
