Galgo

The galgo is a traditional Korean drum. The drum has an hourglass-shaped wooden body and two drum heads of identical diameter, similar to the janggu. Compared to the janggu, the galgo is fitted with a sound-adjusting funnel that is different. The galgo uses thinner drum skins and is struck with two bamboo sticks, chae; the mallet shaped gungchae is not used. The pitch of the drum can be controlled on both sides of the drum rather than only one pitch per-side for the janggu.
