C# m(add9) — Electric Piano
C# m(add9) as keyboard voicings — tones named, budget honest, sound on tap.
C# m(add9) is built from C# – D# – E – G#. On the Electric Piano those tones land as real keys, and every chart below names the tone under each one — root position first, then the shapes that earn their place: inversions, the open spread, the 1-3-7 shell.
The Electric Piano offers a voice for every one of its 73 keys (E1–E7), so voicing choices here are musical, not forced: inversions for smoothness, shells for clarity, open spreads for width.
Under this keyboard's own voice architecture the engine reports: all 4 notes fit — root, 9th, b3, 5th.
