G on the E9 Pedal Steel

All 62 qualities on the root G, in 10 families, drawn for this chair. Most country songs use three or four of them; the rest are here for the turnaround that reaches further.

The pedal steel chair carries the intro hook, a pedal-bend fill between lines, and a long pad holding the chorus up. The bar lies straight across 10 strings tuned to E9, and the chord is whatever those strings sound under it — until a foot or a knee retunes one of them, which is how the next chord of a song usually arrives without the bar moving at all.
