I Would Like To Learn A Tune But Need Help in Tunes /Songs Posted February 5, 2017 · Edited February 5, 2017 by Mary B Gary Coover published "Amazing Grace" in his Civil War songbook. He made Youtube videos of those tunes. He plays the tune fairly slowly with a clear view of the right hand. The tune is in the key of C. I looked at a Gospel Song book by Ondrej Sarek on Amazon. On the US Amazon website, the 20 button version lets you "look inside." Amazing Grace is shown in the key of C. There is a youtube video of this tune by a Japanese woman named Akane Sato. Edited to add the information about the Ondrej Sarek book and Akane Sato video.
