B Major 7 (Bmaj7) Chord Inversions: All Four Positions
B major 7th chord inversions: four positions, Bmaj7, Bmaj7/D#, Bmaj7/F# and Bmaj7/A#. Same four notes (B D# F# A#), a different one in the bass. Below: each position on the keyboard, a one-look rule to tell them apart, fingering and a I-vi-ii that uses them.

Spot each Bmaj7 inversion in one look
Look for the two notes that sit next to each other: none in root position, at the top in the 1st inversion, in the middle in the 2nd, at the bottom in the 3rd.
| Position | Bass | Name | Figured bass | Rule |
|---|---|---|---|---|
| Root position | B | Bmaj7 | 7 | no neighbours: four notes evenly stacked (major 3rd + minor 3rd + major 3rd) |
| 1st inversion | D# | Bmaj7/D# | 6/5 | neighbours at the top (minor 3rd + major 3rd + minor 2nd) |
| 2nd inversion | F# | Bmaj7/F# | 4/3 | neighbours in the middle (major 3rd + minor 2nd + major 3rd) |
| 3rd inversion | A# | Bmaj7/A# | 4/2 | neighbours at the bottom (minor 2nd + major 3rd + minor 3rd) |
B major 7th chord: all four inversions
The lowest note names the position; the chord is still Bmaj7.
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#, A#
- 1st inversion: starts on D#, a black key; black keys: D#, F#, A#
- 2nd inversion: starts on F#, a black key; black keys: F#, A#, D#
- 3rd inversion: starts on A#, a black key; black keys: A#, D#, F#
Move through Bmaj7 → G#m7 → C#m7 without jumping
This is why pianists learn seventh-chord inversions: Bmaj7 → G#m7 → C#m7 keeps the hand in one place.
- From Bmaj7 to G#m7: B stays, D# stays, F# stays, A# → G#.
- From G#m7 to C#m7: B stays, D# → C#, F# → E, G# stays.
Fingering for Bmaj7 in every position
| 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 |
