Harmonic Highlights
- Fluid alternation between the established i-v minor progression and a sophisticated minor plagal cadence (i to VImaj7#11).
- Integration of diatonic minor ii-V movements with highly chromatic, descending dominant chord sequences (e.g., D7b5 to Db7, B7 to Bb7b9).
- Frequent use of altered dominant chords (Eb7b9, D7b5, Eb7#9) and non-functional chromatic major chords (Cmaj7#5) for intense color and tension.
Improvisation Focus Ab Harmonic Minor scale, emphasizing its use over altered V7 chords.
Difficulty Rating 5 (Advanced) - The dense chromaticism, complex altered dominants, and non-functional chord movements demand a sophisticated harmonic understanding.
