Progressions in G — Organ

G major harmonizes to G – Am – Bm – C – D – Em – F#°; G minor to Gm – A° – Bb – Cm – Dm – Eb – F. Each chord links to its Organ 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.
