D m7b9 — E9 Pedal Steel

D m7b9 stacks D – Eb – F – A – C, and with every pedal up and every lever at rest no bar position on the E9 Pedal Steel sounds that set: at every fret, and on every short slant, a tone it needs is missing or too few strings carry it.

A pedal steel does not stop there. With C pedal engaged, a straight bar at fret 1 spells it — one change is the fewest it takes, and the copedent page lists every position, 7 in all.
