The Clever Way to Learn & Practice Bluegrass Music
This is a very simplified melody. It leaves out pickup notes, and uses a simple rhythm, but still follows the melodic arc of the original. Strive for even timing. When practicing, play several times through. Play until it's easy, then play a bit more.
After you get a hang on the basics, then try out a few licks! There are some nice Scruggs Style and Two Finger variations here. Each lick uses a bit of the melody and a Scruggs or Two finger technique to fill out the sound in a really nice way. They shouldn't be to tough. Use the focus feature to practice individual licks before trying it with the song.
