I've been trying to learn this song ever since I heard it on "Gods and Generals". It's really beautiful on the psaltery. Since I also play the dulcimer and other instruments, I haven't had much trouble with finding songs I like. It's like playing a tune on the piano. Once I learn the song, I no longer need sheet music. If anyone needs a song and I have it, I'd be glad to share it.
I also have You Raise Me Up which has been sung by several well-known performers.
