LEARN "Creep" on Seagull Merlin or Strumstick in G | Dulcimer Guitar
Time to learn another rock standard: "Creep" by Radiohead (1993) It's only got 4 chords in one progression for the whole song. That's it, and because one of those chords can't be played on a diatonic instrument, it's even easier than it sounds (which was already pretty easy).
One neat thing to note about this one is the original recording is in G, so you can play along with Radiohead if you have a G-tuned instrument! If you don't have a G tuning, check out the Free Transposition Guide and change the key.
I did a brief cover version of this one using both a Seagull Merlin and a pickin' stick dulcimer (fancy editing), if you want to see it in action.
