This article examines the process of combining three distinct traditional music cultures in Pattani, Thailand, into one piece of music. The author was the music director of the “Hoamroang Sam Prasan” (Overture: Harmony of the Three). Since the three musical traditions – Nora, Rong Ngeng and Digir Hulu, and Chinese drums ensemble – are similar yet different, the work was both easy and difficult. As someone with long experience in intercultural music, I developed a distinct way to do collaborative work. I seek to ensure musicians contribute their best to the piece, establish bonds of trust to co-operate, so they are willing to share in different ideas and training. The project drew the best from traditional musicians so they could develop new work on their own terms with their own musical abilities in a mode I call “conservative contemporary music.” Both artists and audiences could better appreciate the vitality of different musical traditions and their lively interactions more fully.
