Harmonic Highlights:
- Frequent use of minor key characteristic chords like bIIImaj7 (Ebmaj7) and bVImaj7 (Abmaj7), alongside the i and iiø7-V7b13 progression.
- Prominent secondary dominant resolutions, such as F7 to Bb7 and Bb7 to Ebmaj7, expanding the harmonic landscape.
- A distinctive Abm7-Db7 progression, functioning as a sophisticated backdoor dominant (Db7) resolving to Ebmaj7 (bIIImaj7).
- The C7b13 chord specifically highlights the V7b9/b13 quality common in minor key dominant resolutions.
Improvisation Focus: Navigating the harmonic minor scale for the tonic and V chords, and applying altered scales to secondary and backdoor dominants.
Difficulty Rating: 3 (Intermediate). The minor key tonality, various secondary dominants, and the backdoor ii-V progression require a solid understanding of jazz harmony beyond basic major key progressions.
