How to play BbmMaj9
Take the four notes stacked as close together as they go, then drop the second voice from the top an octave. The gap it opens is what makes the chord sound like a chord rather than a cluster.
It lands on four adjacent strings, which is why it is the workhorse voicing on guitar.
BbmMaj9 has 7 of them, on the bottom four strings, the top four strings and the middle four strings, from the 2nd fret up to the 11th — every inversion the chord has: Bb in the bass, Db in the bass, A in the bass and C in the bass. The one to learn first is the C shape at the 2nd fret.
3 of them sit on the top four strings, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with 6475xx — no barre and low, at the 4th fret. None of the shapes for BbmMaj9 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 3 of the 6 need a barre. Together they cover the neck from the 1st fret to the 14th.
