C# m(maj7)add13 — E9 Pedal Steel
C# m(maj7)add13 has no bar or slant position on the E9 Pedal Steel with the pedals up.
C# m(maj7)add13 stacks C# – E – G# – A# – B#, 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 B pedal + LKL engaged, a straight bar at fret 7 spells it — 2 changes is the fewest it takes, and the copedent page lists every position, 9 in all.
