The Ma'yong theatre of Malaysia, though little known outside the province of Kelantan where it once flourished, is a rare example of a court entertainment which changed into a popular performance within the relatively brief period of about fifty years. Ma'yong, now performed only two or three times a year by wives of rice farmers in the remote villages of Kelantan, carries little evidence of its court origins; however, the magical propitiatory function which seems to have been associated with it from the beginning is still recognized. Furthermore, Ma'yong is unique in that all the leading roles, both male and female, are taken by women, while only the parts of the servant-clowns, or peran (generally two in a given play), are played by men. This introduction to Ma'yong is based on a three-month expedition I made in 1968 to record this theatre and its music on video tape.
