Watch the Gentle Annie online guitar lesson by Stephen Bennett from Harp Guitar Basics
This is all pretty straightforward stuff here! Here's your tuning (from the lowest pitched sub-bass string to the highest): GABCDG
The regular guitar is tuned to standard: EADGBE
Go ahead and do the magic C major chord a couple of times before you dig into this tune. Here's what you do: play simultaneously the C sub-bass, the high G sub-bass and a harmonic at the 12th fret of the 6th string. OR instead of simultaneously - play them one after the other quickly in an arpeggio fashion. Beautiful, no?
Now learn the verse.
