Harmonic Highlights:
- Employs the classic minor ii-V-i progression (Dm7b5-G7#9-Cm) with characteristic altered dominant tensions (#9).
- Features a temporary shift to the relative major (Ebmaj7) via a ii-V-I (Fm7-Bb7-Ebmaj7) within the minor key framework.
- Utilizes secondary dominant function, such as A7b5 leading to subsequent ii-V patterns, creating harmonic interest.
- Frequent ii-V movements, including those targeting both the minor tonic (Cm) and the dominant (Gm) of the key.
Improvisation Focus: C Harmonic Minor scale (and its related modes).
Difficulty Rating: 4 (Intermediate-Advanced). The frequent ii-V changes, relative major excursions, and altered dominant tensions require solid harmonic understanding and agile navigation.
