Despite its name, the slit drum isn’t actually a drum in the traditional sense. It’s a type of idiophone, an instrument that produces sound through the vibration of its body, rather than strings or stretched membranes. A slit drum is typically made from a hollowed log or wooden box with one or more slits cut into the top. These slits can be shaped in various ways, often resembling an “H” or a series of parallel lines.
When struck with a mallet or stick, the tongues of wood between the slits vibrate, producing rich, warm tones that can carry over long distances.
