Michael Jackson在于80年代的人来说一直都是偶像。 
几年前一直都想知道Michael Jackson -迈克.尔杰克演唱会里那招45度身体前倾，一直都懒去做时间一长就把这事忘记。直到今天得到MJ离开我们，才突然想起此事。所以花了大约一小时时间收集资料。
 

 关于Michael Jackson 45度前倾舞步秘密，做了一下资料收集，图文还有视频在这日子里学习缅怀一下。

美国专利版权US5255452 PDF说明

Discover the secret behind the 45 degree lean in the Smooth Criminal video and in the live performance.
Michael Jackson and two of his costume designers obtained a US patent (US5255452) in 1993 on "Methods and Means for Creating Anti Gravity Illusion". The invention outlines how a special pair of shoes attaches to a stage to allow leaning forward beyond the centre of gravity of the wearer of the shoes. A case study of this patent is presented here.

Background and Prior Art Interesting stage designs, lighting, fog generators, laser light shows, and large video screens have been used by music entertainers and dancers to enhance the appeal of their live and recorded performances.

In the past Michael Jackson had incorporated dance steps in his recorded video performances, wherein he and other dancers would lean forward beyond their center of gravity, thereby creating an impressive visual effect. In the video this effect was accomplished by the use of cables connecting a harness around the dancer's waist with hooks on a stage, thereby allowing the dancer to lean forward at the required degree.

However, since this requires stagehands to connect and then disconnect the cables, it has not been possible to use this system in live performances. Moreover, the cables obviously restricted arm and body movements.

Description of the Invention

The present invention overcomes the above noted deficiencies of the previously employed cable system by providing specialized footwear and
a moveable hitch or post to which the specialized footwear can be detachably engaged to, allowing the footwear wearer to lean forward on the stage, with his or her center of gravity well beyond the front of the shoes, thereby creating the desired visual effect. The hitch or post protrude upwardly through the stage platform at a predetermined time.

  迈克在Smooth Criminal 录影带中表演的身体身体前倾45度，和演唱会中表演的身体前倾45度特技。两项发明早在1993年，迈克都申请了专利，专利号(US5255452)。专利名称“摆脱地心引力的幻想”。最初的”MOONWALK“电影中表演的身体前倾，依靠的是一根系在演员腰间的绳索。当然绳索在MV后期经过加工处理，观众是看不到的。演员身体的前倾的角度，依靠的是天花板的机械控制。那时在MV中甚至可以看到前倾45度+旋转。到后来这个方法，在演唱会中就不现实了。因为系在腰间的绳索根本不可能在现场表演中安装和拆除。其二，提前安装的绳索限制了演员的手臂和身体的舞蹈动作，迈克想到了另外一种方法。。

演唱会中的表演，需要各个环节相互默契配合才能完成。首先需要舞台眩目的灯光，烟雾发生器 ，激光。 

当迈克需要表演特级的时候，MJ就会跟伴舞的演员走近舞台的“特殊区域”，通常这时候该区域的灯光会非常暗。工作人员扮演的“歹徒”会立即上场，手拿炸药表演几秒钟。分散观众注意力，给MJ准备赢得时间。 当MJ准备好的时候，“特殊区域”就会被点亮。迈克前倾诉45度一气呵成！！关键的细节在于MJ那双特制的鞋子，从图里可以看到，鞋后跟于舞台有机械联接，可以把身体支持点牢牢的固定住。
技术细节：演唱会方法克服了，绳索系统的不足，可以使演唱会连贯的进行。从而达到身体重心超越支持点的视觉效果。同时，舞台的“抓勾”系统通过精密仪器的控制，可以准确的适时伸缩，以达到不被发现的目的。特别提请的是：即便如此，也里不开迈克和演员刻苦的锻炼，及精心排练和磨合。离不开强健的背部肌肉身体平衡控制力
