How to play Bm9
Bm9 in 2nd inversion puts F# in the bass instead of B, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.
One of Bm9’s 8 common shapes does this: xx4635.
Start with xx4635 — no barre and low, at the 3rd fret. 1 of the 8 shapes here sits in open position. 5 of the 8 need a barre. Together they cover the neck from the 2nd fret to the 14th.
