Progressions in E — 4-Voice Polysynth

E major harmonizes to E – F#m – G#m – A – B – C#m – D#°; E minor to Em – F#° – G – Am – Bm – C – D. Each chord links to its 4-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.
