- Prominent use of “line clichés” (e.g., Eb, Ebaug, Eb6) over tonic and subdominant chords, creating chromatic movement within static harmony.
- Standard ii-V-I progression to the subdominant (Bbm7 Eb7 Ab) provides familiar harmonic ground.
- A chromatically rich turnaround features minor iv (Abm7), a iiø7-bVII7 (Fm7b5 Db7), leading to V7 (Bb7).
Improvisation Focus: Chord tone outlining with strategic chromatic embellishment.
Difficulty Rating: 3/5. Navigating the line clichés and chromatic dominants requires specific voicings and scale choices beyond basic diatonic improvisation.
