Spot each Abm7 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 | Ab | Abm7 | 7 | no neighbours: four notes evenly stacked (minor 3rd + major 3rd + minor 3rd) |
| 1st inversion | Cb | Abm7/Cb | 6/5 | neighbours at the top (major 3rd + minor 3rd + major 2nd) |
| 2nd inversion | Eb | Abm7/Eb | 4/3 | neighbours in the middle (minor 3rd + major 2nd + minor 3rd) |
| 3rd inversion | Gb | Abm7/Gb | 4/2 | neighbours at the bottom (major 2nd + minor 3rd + major 3rd) |
Fingering for Abm7 in every position
| Position | Right hand | Left hand |
|---|---|---|
| Root position (Ab Cb Eb Gb) | 1-2-3-5 | 5-3-2-1 |
| 1st inversion (Cb Eb Gb Ab) | 1-2-3-5 | 5-3-2-1 |
| 2nd inversion (Eb Gb Ab Cb) | 1-2-3-5 | 5-3-2-1 |
| 3rd inversion (Gb Ab Cb Eb) | 1-2-3-5 | 5-3-2-1 |
Keep the same four fingers for all positions; only the notes under them change.
Move through Abm7 → Dbm7 → Gb7 without jumping
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 Abm7 to Dbm7: Cb stays, Eb → Db, Gb → Fb, Ab stays.
- From Dbm7 to Gb7: Cb → Bb, Db stays, Fb stays, Ab → Gb.
Practise Abm7 in every position
In ChordRunner any inversion of Abm7 counts: play Abm7/Cb, Abm7/Eb or Abm7/Gb and the runner jumps. MIDI keyboard or microphone, both work.
