- Frequent use of the Eb07 diminished chord as a chromatic passing motion (e.g., Em7-Eb07-G7/D), adding tension and color.
- Standard ii-V-I progressions (Dm7-G7-Cmaj7) form the diatonic foundation of the tune.
- Secondary dominant A7b13 (V7/ii) introduces a distinctive altered color and tension, leading effectively to Dm7.
- The Ab7#11 altered dominant presents a complex, possibly tritone substitution, harmonic twist towards the end of the sample.
Improvisation Focus: Navigating altered dominant scales and diminished sounds over secondary dominants and chromatic passing chords.
Difficulty Rating: 4 (Advanced Intermediate). The blend of foundational ii-V-I with sophisticated chromatic diminished chords and altered dominants demands a strong theoretical and aural understanding.
