Khmer classical dance is the form of stylised performance art established in the royal courts of Cambodia exhibited for both entertainment and ceremonial purposes. 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. Known formally as ''Robam Preah Reach Troap'' ( "theater of royal wealth") it is set to the music of a pinpeat ensemble accompanied by a vocal chorus.
