Harmonic Highlights:
- Prominent use of bIImaj7 (Gbmaj7, often #11) creating side-slipping and Lydian color against the F major tonic.
- Frequent altered dominant 7ths (e.g., Db7#5) and chromatic dominant shifts (e.g., Db7 to D7) for heightened tension and angular movement.
- Rapid, non-functional dominant sequences (e.g., B7-A7-D7-G7) generating quick harmonic shifts and temporary tonicizations.
Improvisation Focus: Altered Scale application for dominant 7th chords.
Difficulty Rating: 5 (Advanced). Requires mastery of altered scales and sophisticated harmonic anticipation due to frequent, rapid, non-diatonic chord changes and modulations.
