Pole Drums

Pole drums are large tubes made from cleaned, hollowed logs. Adorned with leather, paint, woven materials, and rope.
==Description==
Pole drums are similar to women’s meal mashing poles in that both are played in an interlocking pattern. Some of the poles are played singly. Others are lashed together in pairs of differing sizes. When pounded on the ground, the different lengths of the drum tubes create different pitches. Although a melody is created by the interlocking pitches, the Na'vi do not use these drums to create specific melodies.
