| Am7 -> D7#9 | Setup (Major Key) | 1 |
- Repeated D69 - C69 establishes a Lydian-infused, non-diatonic whole-step descending motion (V69-IV69 in G), creating an open, modern harmonic texture.
- A chromatic descent through Bm7 - Bb7 - Am7 (iii - bVI7 - ii) leads to the altered dominant D7#9 (V7alt), building tension before resolution.
- The Ab7#11 acts as a prominent bII7 (tritone substitution for D7) with Lydian dominant characteristics, resolving directly to G7, implying a V7-I or blues-tonic resolution.
Improvisation Focus: Altered Dominant Scales.
Difficulty Rating: 4 (Advanced Intermediate). Frequent non-diatonic chords, tritone substitutions, and altered dominants demand a sophisticated understanding of jazz harmony.
