A Major 7 (Amaj7) Chord Inversions: All Four Positions
To invert Amaj7, move the lowest note up an octave: A C# E G# becomes C# E G# A, then E G# A C#, then G# A C# E. Below: each position on the keyboard, a one-look rule to tell them apart, fingering and a I-vi-ii that uses them.

The four positions of Amaj7
Root position starts on A, then C#, E and G#.
Root position: A C# E G#
1st inversion: C# E G# A
2nd inversion: E G# A C#
3rd inversion: G# A C# E
- Root position: starts on A, a white key; black keys: C#, G#
- 1st inversion: starts on C#, a black key; black keys: C#, G#
- 2nd inversion: starts on E, a white key; black keys: G#, C#
- 3rd inversion: starts on G#, a black key; black keys: G#, C#
Amaj7 in a I-vi-ii with inversions: Amaj7 → F#m7 → Bm7
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 Amaj7 to F#m7: C# stays, E stays, G# → F#, A stays.
- From F#m7 to Bm7: C# → B, E → D, F# stays, A stays.
Spot each Amaj7 inversion in one look
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 | A | Amaj7 | 7 | no neighbours: four notes evenly stacked (major 3rd + minor 3rd + major 3rd) |
| 1st inversion | C# | Amaj7/C# | 6/5 | neighbours at the top (minor 3rd + major 3rd + minor 2nd) |
| 2nd inversion | E | Amaj7/E | 4/3 | neighbours in the middle (major 3rd + minor 2nd + major 3rd) |
| 3rd inversion | G# | Amaj7/G# | 4/2 | neighbours at the bottom (minor 2nd + major 3rd + minor 3rd) |
Amaj7 inversions: which fingers
| Position | Right hand | Left hand |
|---|---|---|
| Root position (A C# E G#) | 1-2-3-5 | 5-3-2-1 |
| 1st inversion (C# E G# A) | 1-2-3-5 | 5-3-2-1 |
| 2nd inversion (E G# A C#) | 1-2-3-5 | 5-3-2-1 |
| 3rd inversion (G# A C# E) | 1-2-3-5 | 5-3-2-1 |
Keep the same four fingers for all positions; only the notes under them change.
