C# Major — Organ

C# Major is built from C# – E# – G#. On the Organ 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 Organ offers a voice for every one of its 61 keys (C2–C7), 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 3 notes fit — root, 3rd, 5th.
