哈哈，测试音准和音色的即兴弹奏要具有一定的松弛三要素：首先要把很多事情看得清楚、想得明白。其次就是弹奏上的松弛，不要顾虑原始版本的细节要求；放弃焦虑和暴躁，用深呼吸或者各种适合自身情感转移等调节情绪的方法去弹奏作品。第三就是不要考虑任何人的存在和评价，放弃社会关系的解绑即可弹奏自如……你的technic［技巧］也会跟踪而来。Haha, the impromptu play of test pitch and timbre should have three elements of relaxation: first of all, you should see and think about many things clearly. The second is the relaxation of playing, don’t worry about the detailed requirements of the original version; give up anxiety and irritability, and play the work with deep breathing or various emotional adjustment methods suitable for your own emotional transfer. The third is not to consider anyone’s existence and evaluation. You can play freely by giving up the unbinding of social relations… Your technic [skills] will also be followed.
