In Avatar there is a pretty distinct difference between the film score and the music of the Na'vi. The film score was composed to bring the story together and enhance the film. The music of the Na'vi was more ingrained with the culture that James Cameron created. He spent a lot of time creating a language and a culture, and the tribal music is definitely a part of it.

While the film score uses identifiable instruments that can be found in an orchestra, the music of the Na'vi is based more on singing and "tribal" instruments. The difference between the two is not too hard to spot.
