 Although the traditional Thai performing arts are not as vibrant as they once were, suffering inroads from Western entertainment and generally changing tastes, Thai dance drama is not extinct.What survives displays the elegance of an art form refined over centuries and supported by regal patronage.Aside from folk and regional dances (southern Thailand's Indian-influenced manohra dance, for example), the two major forms of Thai classical dance drama are Khon and Lakhon nai.
