Original Soundtrack Avatar: Music from the Motion Picture

Composer James Horner scored the film, his third and final collaboration with Cameron after Aliens and Titanic. Horner recorded parts of the score with a small chorus singing in the Na'vi language in March 2008.He also worked with Wanda Bryant, an ethnomusicologist, to create a music culture for the alien race. Horner took advice from his assistant, and they put an unusual number of virtual instruments in this project. The first scoring sessions with the Hollywood Studio Symphony, took place in spring 2009. Leona Lewis sang the theme song, "I See You". An accompanying music video, directed by Jake Nava, premiered on MySpace on December 15, 2009.

A bonus track called "Into the Na'vi World" is available exclusively through the official site.It was not included on the physical and digital releases of the soundtrack.

The score was nominated for Best Original Score at the 82nd Academy Awards, but lost to Up. "I See You" was nominated for a Golden Globe in the Best Original Song category for the 67th Golden Globes.
