Wood Block

A wood block (also spelled as a single word, woodblock) is a small, two-toned slit drum made from a single piece of wood and used as a percussion instrument. The term generally signifies the Western orchestral instrument, though it is related to the time-beaters used by the Han Chinese and called ban. For this reason, the Western instrument is sometimes referred to as "Chinese woodblock". Alternative names sometimes used in ragtime and jazz are clog box and tap box.

The orchestral wood-block instrument of the West is generally made from teak or another hardwood. The dimensions of this instrument vary, although it is either a rectangular or cylindrical block of wood with one or sometimes two longitudinal cavities. It is played by striking it with a stick, which produces a sharp crack.

In a drum kit, a woodblock was traditionally mounted on a clamp fixed to the top of the rear rim of the bass drum.
