A short Gm9 routine
- Say the notes out loud while you press them: G, Bb, D, F and A.
- Play Gm7, then Gm9, then Gm7 again, and hear what the 9th adds to the minor seventh.
- Try Gm9 in a rootless shape with the 3rd on the bottom, the position that sits closest to your last chord.
- Last, meet Gm9 mixed with chords you already know, in an order you did not plan.
Keep each session short and frequent and Gm9 will become automatic.
