There seem to be four major theatrical traditions in Southeast Asia: the Eastern, strongly influenced by Chinese theatre and found in the coastal region of Vietnam; the Southern, previously Hindu-Buddhist and now Moslem, covering parts of Indonesia and Malaysia; the Central, Hindu-Buddhist, found in Thailand, Laos, and Cambodia; and the Western, more strictly Buddhist than the Central tradition and found chiefly in Burma and Ceylon. The traditional theatres of the Southern, Central, and Western areas share many features: they are commonly nightlong performances, done outdoors on a temporary bamboo stage, accompanied by a mainly percussive orchestra; they use either live actors or puppets; and dialogue and action are usually improvised around Indian epics and religious stories.
Yet there are important differences even within the geographical areas. For example, in the South, shadow puppets are comparatively small, with articulated arms, and operated by a single puppeteer, or dalang. In the Central area, puppets are large, not articulated, and operated by a number of dancers; the dalang sits at the side of the screen narrating the story.
