Each skin/side produces a different pitch. The higher pitched side is played with bamboo stick and the deeper side is played with a round-beater head or an open hand. The Janggo symbolizes rain.   The Buk is made of two thick pieces of cowhide lashed to a wood body with a length of rope and usually serves the role of a bass drum. The Buk symbolizes clouds.
