In the state of Kelantan, after the harvesting of paddy, the playing of rebana ubi by villagers is a popular pastime. A rebana ubi is a giant drum measuring one metre in diametre and weighing 100 kg. It is made from a hollowed-out log and is painted in bright colours. Bamboo sticks decorated with tinsel and flowers fan out from its centre like the spokes of a bicycle. The drum produces a thunderous roll when beaten with a stick. In a competition, players in traditional costumes compete in teams of six who play different sized drums. They are often dressed in traditional tunic and headgear, which enhances the gaiety and excitement of the event. They beat the drums continuously for 30 minutes, producing complex rhythms in harmony. Judging is based on the complexity and consistency of the beat and synchronized movements of the players.
