The study of Thai theatre has always been separated into independent issues focus-sing upon narrow and indepth areas. This research intends to investigate the various elements that contributed to the development of Thai theatre from a broad perspective. 

Thai theatre is deeply rooted in song, dance and music. It has both a ritualistic and entertainment function. These functions reflect the Thai way of life which is based primarily upon the agrarian cycle season. Animist, Hindu and Buddhist rites require certain kinds of performing arts as a means of communication and enjoyment. Thus, song dance and music have always been important parts of Thai cultural since ancient times.
