Rods or rod sticks each consist of a 30-45cm long composite of about 7 to 20 thin sticks made of wood or plastic, which is held in shape with a sturdy plastic jacket. Occasionally there is a movable ring to change the strength of the rod assembly and thus the sound properties. Due to the simultaneous appearance of the individual sticks, the sound is softer than with conventional drum sticks. The rods differ in the number and thickness of the individual rods.
