G Jazz ii–V–I
ii – V – I progression in G major
G Jazz ii–V–I — ii – V – I
The G ii–V–I progression (Am – D – G) is the most important cadence in jazz. The subdominant provides motion, the dominant creates tension, and the tonic delivers resolution. With seventh chords (Am7 – D7 – GMaj7), it is the definitive jazz sound.
