What A♭mM7 is built from
Counting up in semitones from A♭:
| Note | Interval | Semitones from root |
|---|---|---|
| A♭ | root | 0 |
| C♭ | minor third | 3 |
| E♭ | perfect fifth | 7 |
| G | major seventh | 11 |
Move all four of those the same distance and you get the same chord on another root — that is what the minor-major seventh formula 0 – 3 – 7 – 11 means.
How to play A♭mM7
All six strings are played. Lay your first finger flat across fret 4 and let the other fingers take the notes above it. The shape runs from fret 4 to fret 6.
All four strings are played. Nothing is higher than fret 3, so it sits in first position.
Play A♭, C♭, E♭ and G together. That is two white keys and two black.
Numbers in the grids are frets. Where a number is printed beside a grid, that is the fret the top row stands for; otherwise the thick bar at the top is the nut. A circle above a string means play it open, a cross means leave it out.

A♭mM7 on the stave
The same four notes written on a treble stave, spelled the way a minor-major seventh is spelled — one letter for every other step, with whichever accidental reaches the pitch. That is why it reads A♭, C♭, E♭ and G, and not the same sounds written some other way.
Which keys A♭mM7 belongs to
No major scale contains all four of these notes. It does sit inside the harmonic minor scale, which is where it is usually met:
- A♭ harmonic minor, on degree i(♮7)
