Classical dance, including the famous 'Apsara dance,' has a grounded, subtle, even restrained, yet feather-light, ethereal appearance. Distinct in its ornate costuming, taut posture, arched back and feet, fingers flexed backwards, codified facial expressions, slow, close, deliberate but flowing movements, Classical dance is uniquely Khmer. It presents themes and stories inspired primarily by the Reamker (the Cambodian version of the Indian classic, the Ramayana) and the Age of Angkor.
