A vertical, cylindrical drum (known as a huehuetl, or "venerable old man" in Náhuatl), made from a hollowed log carved with geometric and other patterns, and painted red with yellow and black edging. A ribbon sash is tied around the top of the drum. Three legs are carved from the frame of the instrument in a "sawtooth" pattern. Families of these drums vary in size, from small to massive (tlalpanhuehuetl).
