The standard grips this chord is usually shown with.
Gm7 is G, Bb, D and F — Gm with the flat seventh added.
It sounds smooth and unhurried. The ii of every major key, so most progressions you already know begin on one of these.

| G | Bb | D | F |
|---|---|---|---|
| 1 | ♭3 | 5 | ♭7 |
Pre-dominant — the ii of a major key, and a tonic in its own right.
Also written Gmin7, G-7 or G minor 7. The same chord either way; which spelling you meet depends on who wrote the chart.
Gm7 in 2nd inversion puts D in the bass instead of G, 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 Gm7’s 6 common shapes does this: x-x-12-12-11-13.
Start with xx5766 — no barre and low, at the 5th fret. None of the shapes for Gm7 uses an open string, so every one of them is movable; the lowest sits at the 3rd fret. 2 of the 6 need a barre. Together they cover the neck from the 3rd fret to the 13th.
