谭正璧先生在《话本与古剧》中对《夜半乐打明皇》题目的解释为:“‘夜半乐’为词调名。‘打’字与‘打字谜’的‘打’字同义。”这个“打”字,乃习惯上各种动作的代称,如:“打水”、“打草稿”之类,不含敲击、拍打之意。文章认为,《打青提》、《夜半乐打明皇》等剧目中的“打”字应源于中国古代戏曲表演中的“打诨”传统与扮演人物之意。 Mr. Tan Zhengbi’s interpretation of the title of “Midnight Music Ming Ming Huang” in “Scripts and Ancient Operas” is: “Midnight Music” is the name of the tune. “打” is synonymous with “打字” in “Typing” “” This “fight ” character, is customary on behalf of all kinds of action, such as: “water”, “draft” and the like, excluding percussion, flapping meaning. The article holds that the words “打 打” in repertoire such as “Playing the Green Youth and Playing the Midnight Music” should originate from the tradition of “打 诨” in Chinese ancient opera performances and the meaning of playing the characters.
