This piece uses the slide at the twelfth fret to play the
main riff followed by a strum on the open strings for 3 beats.
This covers 2 bars in all - this section then repeats to give the first four bars on a D chord.
We then get a shuffle rhythm at the fifth fret for two bars on a G chord.(using L/H fingers one and three)
Note - if you are using the slide on a finger other than your pinky you may not be able to play this - in which case just strum the rhythm here.
Repeat the first two bar riff for two bars on a D chord.
The slide gets an A chord at the seventh fret for one bar - followed by :-
The slide at the fifth fret giving a G chord for one bar.
Finally a two bar rundown ( using L/H 1st finger ) followed by a seventh fret chord which leads back to the beginning.
This is called the Turnaround.
