How to find G7 on the keyboard
- G is the white key between the first and second of the three black keys.

Fingering
In root position, play G7 with the right hand using fingers 1, 2, 3 and 5 (thumb, index, middle and little finger); with the left hand, use 5, 3, 2 and 1. Keep your wrist level and your fingers curved, and press the keys at the same moment so the chord sounds as one.
Inversions
The same notes can be stacked in a different order. Each inversion moves the lowest note up an octave.
- Root position, the root in the bass: G – B – D – F. Right hand 1-2-3-5, left hand 5-3-2-1.
- First inversion, B in the bass: B – D – F – G. Right hand 1-2-4-5 is a common choice, left hand 5-4-2-1 is a common choice.
- Second inversion, D in the bass: D – F – G – B. Right hand 1-2-4-5 is a common choice, left hand 5-4-2-1 is a common choice.
- Third inversion, F in the bass: F – G – B – D. Right hand 1-2-4-5 is a common choice, left hand 5-4-2-1 is a common choice.
Chords that sit next to each other in a key often share one or two notes, so choosing the right inversion can keep your hand almost still when the chord changes.
How G7 is built
G7 has a G major triad (G, B and D) with a minor seventh on top, F, ten half steps above the root. The added seventh makes the chord restless. B and F are six half steps apart, a tritone, and that tension pulls the chord toward C: the 3rd, B, tends to rise a half step and the 7th, F, to fall.
