爵士乐早期与古典音乐有着千丝万缕的联系。应该是从古典音乐中叛逆出来的，如何叛逆的？
一方面是黑人音乐家的自然颜色，一方面是白人音乐家的叛逆和创新。
因此，美国古典音乐在那个时期，有不少将爵士乐高雅化的段落，融入大部头的严肃音乐作品。证明爵士乐实际上拥有黑白两个根。实际上，爵士乐的技巧高度和精致程度的确可以和古典音乐较劲，不过，是建立在叛逆的自由基础之上而已。
Summertime' quickly caught on as a jazz standard thanks to its bluesy chords and was recorded by many of the great jazz vocalists, including Billie Holiday and Sarah Vaughan. A version of Porgy and Bess from 1957 saw two legends collaborate on 'Summertime'.Sep. 26, 2014
