D Chords — 4-Voice Polysynth

All the D qualities, voiced straight onto the keys — the budget line under each chart does the explaining.

Every quality Keys Warrior charts on the root D, voiced for the 4-Voice Polysynth: 10 families running from the plain triads out to the extended and altered colors.

The 4-Voice Polysynth allots 4 voices across its 49 keys (C2–C6): enough for most qualities, but the extended colors make the reducer earn its keep — each chart shows the arithmetic.
