"The Gold" by Manchester Orchestra is in the key of D, so you can play along with the recording! Aside from the intro lick (melody) you can play this one very easily (and correctly) with just 1-Finger!
Johnny Cash's "Hurt" is an eerie, haunting classic that revived his career. Check out my cover of it on a Seagull Merlin Stick Dulcimer Guitar in "D". Enjoy!
