I have always been enamored of southeast Asian "classical" dance. Much of it, if one reads something of its history, is actually rather recent in its current form. The dance of Cambodia/Kampuchea had to be reconstructed following the devastation of the Khmer Rouge horror, and the Bharatanatyam dance of India today is also a reconstruction of perceived "ancient" Indian dance of many centuries back in time, as is likely true for Balinese dance. Worldwide, a lot of "folkloric" dress, art, music, dance is in some sense a product of 19th or early 20th century re-imagination or even re-invention--the case of Scotland and Sir Walter Scott and friends, and George IV comes to mind. But that is no impediment to my enjoyment of the dancing in question. Attractive, supple, highly-trained, beautifully dressed young women gravely executing their memorized steps and poses in exacting detail, can never fail to interest me.
I'll start here with this Cambodian/Kampuchean example. It is very slow, calm, measured. The details of hand and foot position and attitude are obviously of central importance to the dance's proper execution, and it's interesting to compare this with, say, Irish dance where the body is held rigidly immobile and the focus is on footwork alone.
