What is the name of the guitar music playing over the end credits

Theres a you tube video of it- a guy fell in love with it and plays it there. I will try to find the link for you or have a search on you tube. I agree- its beautiful

Don't know the music specifics but watched the end last night after many years. The music (and the end) made me cry. I'll have to check netflix and watch the movie again. Great chemistry Costner and Stowe!
