B7 Chord Inversions: All Four Positions
B7 has four inversions because it has four notes: root position B D# F# A, then D# F# A B, F# A B D# and A B D# F#. Each one is still B7. Learn to spot each position at a glance, then use the nearest one to move between chords.

B7 inversions on the piano
Root position starts on B, then D#, F# and A.
Root position: B D# F# A
1st inversion: D# F# A B
2nd inversion: F# A B D#
3rd inversion: A B D# F#
- Root position: starts on B, a white key; black keys: D#, F#
- 1st inversion: starts on D#, a black key; black keys: D#, F#
- 2nd inversion: starts on F#, a black key; black keys: F#, D#
- 3rd inversion: starts on A, a white key; black keys: D#, F#
B7 in a ii-V-I with inversions: F#m7 → B7 → Emaj7
Each chord uses the position nearest to the one before, so the hand barely moves and most notes step by one or two keys.
- From F#m7 to B7: C# → B, E → D#, F# stays, A stays.
- From B7 to Emaj7: B stays, D# stays, F# → E, A → G#.
How to tell the B7 inversions apart
One rule: find the pair of neighbouring notes. Its place tells you the inversion, and its upper note is the root.
| Position | Bass | Name | Figured bass | Rule |
|---|---|---|---|---|
| Root position | B | B7 | 7 | no neighbours: four notes evenly stacked (major 3rd + minor 3rd + minor 3rd) |
| 1st inversion | D# | B7/D# | 6/5 | neighbours at the top (minor 3rd + minor 3rd + major 2nd) |
| 2nd inversion | F# | B7/F# | 4/3 | neighbours in the middle (minor 3rd + major 2nd + major 3rd) |
| 3rd inversion | A | B7/A | 4/2 | neighbours at the bottom (major 2nd + major 3rd + minor 3rd) |
B7 inversions: which fingers
| Position | Right hand | Left hand |
|---|---|---|
| Root position (B D# F# A) | 1-2-3-5 | 5-3-2-1 |
| 1st inversion (D# F# A B) | 1-2-3-5 | 5-3-2-1 |
| 2nd inversion (F# A B D#) | 1-2-3-5 | 5-3-2-1 |
| 3rd inversion (A B D# F#) | 1-2-3-5 | 5-3-2-1 |
Keep the same four fingers for all positions; only the notes under them change.
Practise B7 in every position
In ChordRunner any inversion of B7 counts: play B7/D#, B7/F# or B7/A and the runner jumps. MIDI keyboard or microphone, both work.

What are the inversions of B7?
Root position B D# F# A, 1st inversion D# F# A B (B7/D#), 2nd inversion F# A B D# (B7/F#) and 3rd inversion A B D# F# (B7/A).
How do I recognise the 3rd inversion of B7?
The seventh, A, is in the bass and sits right next to the root B above it: the pair of neighbouring notes is at the bottom.
Can I practise B7 inversions with a MIDI keyboard or microphone?
Yes. ChordRunner detects a USB MIDI keyboard automatically and also hears a piano through the microphone; every inversion of B7 counts.
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.
