- Extended ii-V functionality featuring altered dominant voicings (b9, #11) and chromatic embellishments.
- Prominent tritone substitutions and non-functional dominant movements creating unexpected resolutions (e.g., D9#11 to Dbmaj7, E7 to Dbmaj7).
- Frequent, distant modulations (e.g., F#m7-B7-Emaj7) and parallel minor/diminished tonalities, moving far from the Ab tonic.
- Strategic use of diminished chords (Ab07, A07, G07) to build tension and provide chromatic connectivity.
Improvisation Focus: Navigating intricate chord changes with an emphasis on chromatic alterations and voice leading.
Difficulty Rating: 5 (Advanced). Requires deep understanding of advanced harmonic substitutions, distant modulations, and navigating complex chromaticism.
