D7 Chord on Piano (D Dominant 7th)
D dominant 7th (D7) is spelled D - F# - A - C. It sounds like D with an extra C, the note that gives it its restless dominant colour. Here you will find its inversions, both hands and the chords it belongs with.

Where D7 goes
- D7 is the V7 chord of G major and of G minor: it pulls into G / Gm.
- In a ii-V-I in G major it is the middle chord: Am7 → D7 → Gmaj7.
- Between F# and C there is a tritone, the interval that creates the pull. Ab7 has the same two notes, so it can replace D7 (tritone substitution).
D7 inversions on the keyboard
A seventh chord has four notes, so it has four positions. Each one is still D7.
Root position: D F# A C
1st inversion: F# A C D
2nd inversion: A C D F#
3rd inversion: C D F# A
A 5-minute D7 routine
- Play D, F#, A, C slowly in root position and say "D7" each time.
- Climb the four positions: D F# A C, then F# A C D, A C D F# and C D F# A, and back down.
- Play it in its ii-V-I, Am7 → D7 → Gmaj7, four beats per chord.
- Finally meet it in random order between other chords, with a check on every note.
Short daily rounds fix D7 in memory faster than one long practice a week.
How D7 differs from the other 7th chords on D
Play the four in a row and listen to each colour.
Playing D7 with each hand
| Hand | D | F# | A | C |
|---|---|---|---|---|
| Right hand | 1 (thumb) | 2 | 3 | 5 (little) |
| Left hand | 5 (little) | 3 | 2 | 1 (thumb) |
Play D7 broken first, D, F#, A, C one by one, then together: a wrong key stands out.
D7 without the fifth
Drop the fifth and keep D F# C: root, third and seventh. Pianists use this shell voicing in the left hand, because those three notes already say "D7".
Make D7 automatic
Knowing D7 on paper is step one. ChordRunner makes you find it fast, mixed with other chords. MIDI keyboard or microphone, both work.

Press D, F#, A, C together. Right hand 1, 2, 3, 5 with the thumb on D; any octave and any order of those notes is still D7.

Root position D F# A C, 1st inversion F# A C D, 2nd inversion A C D F# and 3rd inversion C D F# A. Every position is still D7.
Where does D7 go?
D7 is the V7 chord of G major and of G minor: it pulls into G / Gm. In a ii-V-I in G major it is the middle chord: Am7 → D7 → Gmaj7.
Can I practise D7 with a MIDI keyboard?
Yes. In ChordRunner a USB MIDI keyboard is detected automatically, and an acoustic piano works through the microphone. D7 counts in any inversion, as long as D, F#, A, C sound together.
Your instrument is the controller.
ChordRunner is a browser game that teaches piano and guitar chords: a chord appears on screen, you play it on a real instrument, and your runner jumps. MIDI keyboard or microphone, both work.
