Query: Didn't work for us

Other reviews said that this was a quick easy way to learn to play so I bought it for my 14 year old son who plays percussion and wanted to expand to hammered dulcimer. He didn't get it. When I tried to help, and I play piano, I couldn't figure it out either. Maybe we are too bound by reading music but we didn't get it.
