Cool. I'm going to have one of my high school students do it in D then. I originally learned it in F when I was in high school. But down a third is perfect for this one particular student.
Glad I could help. I learned it first in D and move on to F later. It's good for getting younger, less experienced players making MUSIC early on, rather than torturing them with something that may or may not discourage them. Enjoy!
