Harmonic Highlights:
- Initial progression (Gm, Eb7, D7b9) firmly establishes a G minor key area (i-bVI7-V7b9), contrasting the given G major.
- The
Gm, Gmb6, Gm6, Gmb6sequence creates a distinct minor color by emphasizing the b6 and natural 6th, adding internal chromaticism to the tonic. - A sequential altered dominant chain (
B7b5, E7, A7b5, D7b9) generates strong harmonic momentum leading to the primary dominant. - The repeated
D07/Db(functioning as Dbdim7) serves as a persistent #iv°7 passing chord or leading-tone diminished to the V7b9, enhancing chromatic tension.
Improvisation Focus: G Aeolian scale, incorporating chromatic alterations for dominant chords.
Difficulty Rating: 4 (Advanced Intermediate). The combination of specific minor modes, complex altered dominants, and a recurring diminished chord requires sophisticated harmonic understanding.
