Harmonic Highlights

  • Frequent use of modal interchange via the iv6 (Cm6), introducing a poignant subdominant minor coloration borrowed from the parallel G minor scale.
  • Secondary dominant chains, such as E7 to Am7 and A7 to D7, which create strong directional movement toward the ii and V chords.
  • A minor ii-V (Bm7b5 - E7) sequence that temporarily shifts the harmonic center toward the supertonic (Am7).
  • Chromaticism provided by the F#ยฐ7, functioning as a leading-tone diminished chord ($vii^\circ7$) resolving back to the tonic Gmaj7.

Improvisation Focus The G Melodic Minor scale is the most critical tool for navigating the Cm6 chord, while chord-tone targeting is essential for the secondary dominants.

Difficulty Rating 2/5: The progression follows predictable jazz logic with standard secondary dominants, though the modal borrowing requires a solid understanding of non-diatonic tones.
