Harmonic Highlights
- Frequent ii-V-I progressions (Gm7-Cm7-F7-Bbmaj7) establish and reinforce the Bb major tonality.
- The Db07 chord functions as a chromatic diminished (bIIIdim7) leading into Cm7, adding tension and a sophisticated color.
- A prominent B7#5 chord acts as a highly altered dominant or tritone substitute, creating a distinctive chromatic pull before resolving to Cm7 (ii).
Improvisation Focus Altered Dominant scales and chromatic embellishments.
Difficulty Rating 4. The presence of unique altered dominants and passing diminished chords requires a strong grasp of chromaticism and advanced harmonic substitutions.
