Harmonic Highlights:
- Prominent use of diminished chords (e.g., F#07 leading to Gm7) creating chromatic passing harmony and strong voice leading.
- Recurring ii-V progression (Bbm-Eb7) strongly tonicizes Ab major, indicating frequent temporary modulations away from the home key of Bb.
- The Am7 - Ab07 - Gm7 sequence features a chromatic descending bass line, intensified by the use of the diminished chord for added tension and resolution.
Improvisation Focus: Navigating temporary modulations and applying appropriate scales (e.g., half-whole diminished) over complex chord alterations.
Difficulty Rating: 4 (Advanced Intermediate). The frequent, non-diatonic ii-V changes and intricate diminished chord resolutions require strong theoretical understanding and ear training.
