Darcy Farrow is a tragic ballad written by Steve Gillette and Tom Campbell in 1964. It was first recorded by Canadian duo Ian & Sylvia the next year, but really hit it big when John Denver recorded it for his album Rocky Mountain High in 1972. John's arrangement tightened up the chord progression a bit, and started with a great fingerpicking intro. The song is played in Dropped D Tuning and John capoed it to the 3rd fret.
This lesson goes into great detail about the intro, outro, as well as a little variation in the solo, and presents some options about picking patterns that can be used to accompany the verses.
