D# maj13 — Piano

D# maj13 is built from D# – E# – F## – A# – B# – C##. On the 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 Piano offers a voice for every one of its 88 keys (A0–C8), 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 6 notes fit — root, 9th, 3rd, 5th, 13th, 7th.
