This is a great finger picking pattern to learn as although it looks complicated. its not super difficult for even the greenest of players. Once you master it, it sounds delightful.
What Are We Learning To Play?
Firstly, let’s assign the fingers on our strumming hand. Use your thumb for the top two strings (G+C), your first finger for the bottom two (E+A). They will remain for the entire riff. For the fretting hand, we are starting with a CMaj7 chord. Use your first finger on the 2nd fret of the A string.
The 2h3p2 is a hammer-on then pull off. You need to pluck the A string, then use your middle finger to literally “hammer” down onto the 3rd fret. That will cause the note to change pitch. Almost immediately, you then need to “drag” your middle finger back off to reveal the 2nd fret again. The dragging is what creates the sound of the note.
In my opinion, the most testing part of this is the chord changes at the end of each section. Although it may seem counter-intuitive, I recommend using your middle finger on the 2nd fret of the C and your ring finger on the 2nd fret of the A. Then jump your finger up two strings onto the 4th fret of the C string.
That’s going to leave your first and middle finger free to play the 2h3p2 on the next section.
