ii – V – I progression in G# major
G# Jazz ii–V–I — ii – V – I
The G# ii–V–I progression (A#m – 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 (A#m7 – D#7 – G#Maj7), it is the definitive jazz sound.
