- Chromatic diminished chord (F#07) provides tension, functioning as a passing chord to the ii minor (Gm7).
- Sequential ii-V progressions (Am7-D7, Gm7-C7) create extended dominant harmony, delaying tonic resolution.
- Frequent modulation to the subdominant (Bbmaj7) key area via explicit ii-V-I progressions (Cm7-F7-Bbmaj7).
- The minor ii-V-i progression (Em7b5-A7b9-Dm7) introduces a temporary pivot to the relative minor (vi) key.
Improvisation Focus: Fluency in ii-V chord-scales and their altered tensions for navigating temporary modulations.
Difficulty Rating: 5 (Advanced). The rapid harmonic rhythm, frequent modulations, and use of altered dominants require a sophisticated understanding of harmony and improvisation.
