The script of Yaochaji (藥茶記 a well known Beiguan play) includes ten melo-metric tunes (唱腔) which are rendered in the Guluxi (古路戲, the old style theater) of Beiguan theater music in Taiwan. In my graduation concert, six of the ten melo-metric tunes from selected scenes were presented: Caiban (彩板), Liushui (流水), Jinban (緊板), Jinzhongman (緊中慢), Fanliushui (反流水), Jinliushui (緊流水). According to this concert, this paper describes the process of organizing this concert, the ideology, and the description of performance styles. Moreover, comparison and analysis of the script with some regional theaters in China, for instance, Sichuan opera (川劇), Beijing opera (京劇), Liuzi opera (柳子戲), Shaoxing opera (紹興戲) will help to understand the different interpretation of this play. This paper also discusses the use of different words in the titles, based on their original scripts. Furthermore, the six tunes rendered in my concert are divided into two categories, metered and unmetered, to illustrate the different styles. Following Beiguan master Chuang Chin-tsai’s (莊進才) transmission, the six tunes are transcribed into cipher notation and attached to this paper in order to illustrate the methodology of analyses.
