This study examined the background, current contexts and problems of the Mon dance relating to posture, melody and music, dress, performers, dance duration, rituals, and customs. It was found that they were both similar and different, depending on the environment and socio-cultural changes in each area. The need to establish a standard of dance revealed that they were similar in terms of postures, melody, music, dress, performers, dance duration, rituals, and customs.
