Dances with Wolves is the original soundtrack of the 1990 Academy Award and Golden Globe winning film Dances with Wolves produced, directed, and starring Kevin Costner.
The original score and songs were composed and conducted by John Barry.
Barry was brought in to replace him; it was his first score in two years since taking a break due to rupturing his esophagus.
He prepared by listening to American Indian music, but didn't incorporate it into score, believing it should be seen through the protagonist's eyes.
Barry and Costner both envisioned a large and romantic score due to the "feeling of space" in the film.
