A slit drum is a hollow percussion instrument, usually of bamboo or wood, which is made more resonant through one or more slits in the instrument.

Most slit drums have three slits, cut into the shape of an "H". If, as is usual, the resultant tongues are different lengths or thicknesses, the drum will produce 2 different pitches. Pitch represents the perceived Fundamental frequency of a sound
The ends of a slit drum are closed so that the shell becomes the resonating chamber for the sound vibrations created when the tongues are struck, usually with a mallet. Oscillation is the repetitive variation typically in Time, of some measure about a central value (often a point of Equilibrium) or between two or more different states The resonating chamber increases the volume of the sound produced by the tongue and presents the sound through an open port. If the resonating chamber is the correct size for the pitch being produced by the tongue, which means it has the correct volume of airspace to complete 1 full sound wave for that particular pitch, the instrument will be more efficient and louder. An acoustic wave is a weak compression wave (meaning a small pressure change that moves at the Speed of sound.
