War Drum

The war drum is a musical instrument used in ritual dances and for making warning signals by the Na'vi.
==Description==
The different warning rhythms played on it are associated with specific dangers to the Na'vi and are used to signal for help. Because of its association with danger, the drum is also used to accompany ritual prebattle dances.
Some of the warning rhythms played on the drum represent different dangers; other rhythms indicate the direction from which the danger approaches. One rhythm is played when a Na'vi is in mortal danger and in need for help. Na'vi children learn the different signals from an early age.
The more recent incursions by humans necessitated the addition of another warning rhythm. It is theorized that the warning rhythm for humans is based on the Na'vi word skx'awng, highly derogatory term that is more or less analogous to "moron", or "one who does not see."
==Materials and Construction==
The structure is made of branches, covered on both sides with tanned hexapede hides, filled with water, and the beating stick is made from a smoothed branch the size of a Terran baseball bat.
== Role in the Avatar Universe ==
After gathering the clans for the battle against the RDA you can see the drums of war.
One of the unused scenes in the film shows the night before the Battle of the Soul Tree, when the Omatikaya Clan set up a pre-war camp. Among the many musicians who play, among others the Blue Flute, the Pendulum Drums and the Log Drums, there are also Na'vi playing War Drums.
