It is a great privilege for a girl, usually no older than 12 or 13, to be chosen for this role, which requires extraordinary grace, concentration and body control. The dance is usually accompanied by a 20 to 30 person orchestra, or gamelan. The gamelon instruments include large and small gongs, xylophones, drums and frequently a zither-like instrument called a celempung. The girls are wearing identical gold-leaf brocade dresses and crowns adorned with frangipani flowers.
