Harmonic Highlights:
- Prominent chromatic diminished chords (B07, C#07) function as passing harmonies, creating tension and leading tones.
- Strategic use of a ii-V-I progression (C7b9-Fm7-Bb7-Ebmaj7) to briefly establish the subdominant key.
- Incorporation of altered dominants like C7b9, requiring specific scale choices for improvisation.
Improvisation Focus: Navigating diminished scales and arpeggios over chromatic passing diminished chords.
Difficulty Rating: 4 (Advanced). The frequent, non-diatonic diminished and altered dominant chords require precise scale and arpeggio knowledge.
