It is used as practice for the real agung: players either use either one agung a tamlang (hold it with one hand and using the other to strike it with a beater) or using two agung a tamlangs where the other agung is held with one’s feet.
The agung is practiced in advance for the actual performance: participants use either one agung a tamlang by holding it with one hand and hitting it with a beater using the other, or two agung a tamlangs, where the additional agung is grasped with the feet.
