Progressions in C — 8-Voice Polysynth

C major harmonizes to C – Dm – Em – F – G – Am – B°; C minor to Cm – D° – Eb – Fm – Gm – Ab – Bb. Each chord links to its 8-Voice Polysynth voicings, and the page walks the changes with voiceLeadNearest — the engine that picks whichever next voicing moves the fewest keys.

Voice leading is a keyboard player’s home advantage: common tones stay under the same fingers, and only the moving lines move.
