Here's the fingering for this guitar chord:
This inversion has its root on the G string and uses the notes in this order:
- F (the b7th)
- B (the 3rd)
- D (the 5th)
- G (the root)
G7 | C7 | G7 | G7 | C7 | C7 | G7 | G7 | D7 | C7 | G7 | D7
and in other keys, in C:
C7 | F7 | C7 | C7 | F7 | F7 | C7 | C7 | G7 | F7 | C7 | G7
F7 | Bb7 | F7 | F7 | Bb7 | Bb7 | F7 | F7 | C7 | Bb7 | F7 | C7
E7 | A7 | E7 | E7 | A7 | A7 | E7 | E7 | B7 | A7 | E7 | B7
and so on...
Then experiment with playing melodies by changing inversions, you can build tension up and add interest by using different inversions rather than using the same fingering for every guitar chord.
