The chord hiding inside Fm9
The four upper notes of Fm9, Ab C Eb G, are Abmaj7. Play F low and Abmaj7 above it: that is the whole Fm9, and a quick way to reach it.
Building Fm9 from Fm7
Formula 1 b3 5 b7 9. Count from F and every number is a step of the F major scale, and a b lowers it by one key.
Start chord: Fm7
| Note | Step | Interval | Keys from F |
|---|---|---|---|
| F | 1 | root | 0 |
| Ab | b3 | minor 3rd | 3 |
| C | 5 | perfect 5th | 7 |
| Eb | b7 | minor 7th | 10 |
| G | 9 | major 9th | 14 |
A short Fm9 routine
- Find F, then add the other notes one at a time: F, Ab, C, Eb and G.
- Play Fm7, then Fm9, then Fm7 again, and hear what the 9th adds to the minor seventh.
- Try Fm9 in a rootless shape with the 3rd on the bottom, the position that sits closest to your last chord.
- Then test it in random order among other chords: recall under time pressure is what sticks.
Five minutes a day is enough to make Fm9 feel easy.
