Harmonic Highlights:
- Consistently employs the iim7b5-V7b9-im7 progression (Am7b5-D7b9-Gm7) to establish G minor.
- Features temporary modulations to Eb major via its ii-V-I (Fm7-Bb7-Ebmaj7), linking to the relative major’s subdominant.
- Includes a strong, unexpected modulation to Ab major through its ii-V-I (Bbm7-Eb7-Abmaj7), creating significant harmonic distance.
- Chromatic dominant 7th motion, like Eb7 resolving to D7b9, adds sophisticated voice leading.
Improvisation Focus: Melodic minor scale applications, particularly over dominant 7b9 chords and during modulations.
Difficulty Rating: 4 (Advanced) – The rapid modulations to distant keys and frequent altered dominant voicings require sophisticated harmonic awareness.
