即兴表演的观念阐释

作者：周倩雯上海大学数码艺术学院

"即兴"是表演本体性中易被忽略的一项要素。一方面,影像记录手段发明之前的即兴表演无法保存;另一方面,理论界将即兴表演等同于无文本戏剧,对于即兴表演的本体性探究往往止步于"戏剧文本性"之争。本文在阐述即兴表演观念史的基础上,试... 详细信息

"即兴"是表演本体性中易被忽略的一项要素。一方面,影像记录手段发明之前的即兴表演无法保存;另一方面,理论界将即兴表演等同于无文本戏剧,对于即兴表演的本体性探究往往止步于"戏剧文本性"之争。本文在阐述即兴表演观念史的基础上,试图将即兴表演从表演训练方法和预演功能中剥离出来,厘清即兴表演背后的主旨观念:即兴表演包含着对于传统戏剧结构因果链的破坏,代表着对于完整性符号系统和意识形态系统的一种突围方式,其革命性和前瞻性难以被忽略。即兴表演在未来的叙事艺术发展中将获得更为广阔的前景。

从文本到话语再到语境,美国学院派表演教学以清晰的路径标识指引学生走入历史语境,体认经典文本,之后再返回现实语境,以表演艺术反哺现实需求。纽约大学提希艺术学院戏剧系经典戏剧工作室,以西方经典剧目为教学重点,承袭方法派,形成"新古典主义训练法"。经典工作室的教学重点在于表演"行动"与戏剧"文本"的磨合工作,以话语施效功能为圭臬,由排演贯穿至演出阶段,并与美国主流剧团的演员选角标准严格对接,使学生在毕业进入职业生涯前已具备规范、成熟的表演技能和人文素养。

民国时期在华公映的苏联电影《阿比西尼亚》在上海放映时曾引起了一场风波,遭到禁映。《阿比西尼亚》一片因其一波三折的禁映历史,在民国电影放映史中显得颇为特殊。而作为“历史中的电影”,影片的禁映更为当时抗战背景下民族话语的表达提供了合法的舆论场域。在层层递进的舆论声浪间,禁映事件的影响也逐渐爬升到制度层面,为电检会态度的转变和电检制度的调整起到了助推作用。

针对离线测试方法无法对遭受短路冲击后的绕组状态进行在线评估和诊断的问题,提出了一种利用冲击电流下绕组振动的频响函数来表征绕组机械状态的方法。该方法利用振动信号和冲击电流构建了单输入多输出的振动系统,通过自功率谱密度函数获得短路冲击下变压器绕组振动的频响函数,并利用相关系数对多次短路冲击下绕组振动频响函数的相关性进行分析。对一台220kV变压器短路冲击试验的研究结果表明,在多次短路冲击中,不同频响函数间的相关系数与相电抗的偏差之间存在一定的负相关关系,即相关系数随相电抗的偏差增大而降低,相电抗偏差越大,相关系数越低。该方法可以利用短路故障时的录波信息,通过绕组的振动频响函数和两次短路冲击的相关系数来表征变压器绕组的机械状态。

＂放开手脚＂则需要另一种勇气。电影从某种程度而言可称之为对＂物质世界的复原＂,电影的现实主义不仅仅是客观记录的现实题材,还包括历史和当下的人类的内心现实的忠实摹写,不管是何种题材,只要力图逼近＂现实＂,就必然会触及各种试图遮蔽现实的阻力。要拿出司马迁修史的勇气进行电影创作确实很难,但总有人身体力行。上海电影的人文传统应当在这方面敢于突围。
