Harmonic Highlights
- Frequent use of the i minor 7 to bVI major 7 progression (Bbm7 to Gbmaj7), defining a characteristic minor key sound.
- Application of altered dominant chords (F7#9, F7b9) as V7, adding significant tension and chromaticism.
- Deceptive resolution of the V7 chord (F7#9) to the bVII major (Ab), creating harmonic unpredictability rather than a direct tonic return.
- Clear iv minor 7 to V7b9 progression (Ebm7 to F7b9), providing a classic minor ii-V setup.
Improvisation Focus Integrating Bb minor scale variants (natural, harmonic, melodic) with appropriate altered scales for the dominant chords.
Difficulty Rating 4 (Advanced). The blend of minor key modes, altered dominant tensions, and deceptive resolutions demands a sophisticated harmonic understanding and agile melodic execution.
