G m7b9 — Lap Steel

G m7b9 stacks G – Ab – Bb – D – F, and no bar position on the lap steel's six strings in C6 sounds that set: at every fret, and on every short slant, a tone it needs is missing or too few strings carry it.

A fretted instrument would reach for a grip here. A steel has no fretting hand, so this page charts nothing rather than a shape no bar can hold — the qualities this tuning does spell are on the chord list for this root.
