Cambodian dance can be divided into three main categories: Khmer classical dance, folk dance, and social dances. The exact origins of Khmer classical dance are disputed. Most native Khmer scholars trace modern dance forms back to the time of Angkor, seeing similarities in the temple engravings of the period, while others hold that modern Khmer dance styles were learned (or re-learned) from Siamese court dancers in the 1800s.
Khmer classical dance is the form of stylised performance art established in the royal courts of Cambodia exhibited for both entertainment and ceremonial purposes.[161] The dances are performed by intricately costumed, highly trained men and women on public occasions for tribute, invocation or to enact traditional stories and epic poems such as Reamker, the Khmer version of the Ramayana.[162] Known formally as Robam Preah Reach Trop (របាំព្រះរាជទ្រព្យ "theater of royal wealth") it is set to the music of a pinpeat ensemble accompanied by a vocal chorus.
Cambodian folk dance, often performed to mahori music, celebrates the various cultural and ethnic groups of Cambodia. Folk dances originated in the villages and are performed, for the most part, by the villagers for the villagers.[163] The movements are less stylised and the clothing worn is that of the people the dancers are portraying, such as hill tribes, Chams or farmers. Typically faster-paced than classical dance, folk dances display themes of the "common person" such as love, comedy or warding off evil spirits.[163]
Social dances are those performed by guests at banquets, parties or other informal social gatherings. Khmer traditional social dances are analogous to those of other Southeast Asian nations. Examples include the circle dances Romvong and Romkbach as well as Saravan and Lam Leav. Modern western popular dances including Cha-cha, Bolero, and the Madison, have also influenced Cambodian social dance.
