A popular fingerpicking technique often used in Jazz guitar is the bass chord style. This style involves the right hand thumb playing a bass note and the right hand fingers picking a chord.
Example 2 uses the bass chord style over the root six major bar chord G. The right hand thumb plays the root note (G) on the 6th string. The right hand fingers then pick the 4th, 3rd and 2nd strings at the same time. This technique may require a little practice to coordinate cleanly as well as ensuring a correct balance of tone and volume between the three notes.
G
The next example uses several root six major bar chords.
Now a progression that uses the root five major bar chord C. This time the right hand thumb playes the root note (C) on the 5th string.
