A 9b5 — Piano

A 9b5 is built from A – B – C# – Eb – G. 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 5 notes fit — root, 9th, 3rd, b5, b7.
