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 fingerings shown in the diagrams above.
Seventh chords are particularly common in Blues, Boogie and Rock’n’ Roll piano playing. The example below demonstrates a 1st inversion G7 chord played over a typical straight eight boogie left hand pattern.
