B Jazz ii–V–I
ii – V – I progression in B major
B Jazz ii–V–I — ii – V – I
The B ii–V–I progression (C#m – F# – B) is the most important cadence in jazz. The subdominant provides motion, the dominant creates tension, and the tonic delivers resolution. With seventh chords (C#m7 – F#7 – BMaj7), it is the definitive jazz sound.
