The IIm7 – V7 – Imaj7 Chord Progression of the Major scale
Below are the first (Imaj7), second (IImin7) and fifth (V7) scale-tone chords of the major scale.
A typical improvisation practice:
- the Dorian mode over the IIm7 chord
- the Mixolydian mode over the V7 chord, and
- the major scale over the Imaj7 chord.
The D Dorian and G Mixolydian modes are both derived from the C major scale. The same seven notes are therefore used for the entire II-V-I segment.
