Because the G7 chord contains four notes, there are three inversions plus the root position. The following three diagrams illustrate the first inversion (3 5 b7 1), the second inversion (5 b7 1 3), and the third inversion ( b7 1 3 5) of the G7 chord.
The following example uses all the inversions of the G7 chord. Use the correct fingerings as shown in the diagrams.
