Harmonic Highlights:
- Extensive use of secondary ii-V progressions, exemplified by Em7b5-A7b9 functioning as a iiø-V of the dominant (D minor).
- Prominent tritone substitution with Ab7 (bII7) effectively substituting for D7, resolving to Gm7 and providing strong dominant function.
- Frequent temporary modulations, notably a clear ii-V-I progression (Fm7-Bb7-Eb6) establishing the bVI chord (Eb major) as a temporary tonic.
- Incorporates a bVII7 (F7) chord which often functions as a backdoor dominant to the relative major (Bb) or introduces harmonic color.
Improvisation Focus: G Harmonic Minor scale (and its related modes).
Difficulty Rating: 4 - Advanced due to the rapid harmonic rhythm, frequent modulations, and use of altered dominants requiring agile scale and arpeggio navigation.
