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. ]]></termNote><termCreatedDate>2026-03-30 20:28:23</termCreatedDate><relation><relationType>BT</relationType><termId>31308992</termId><termName>music</termName><termType>PT</termType></relation></term>  </Zthes>
