Harmonic Highlights:
- Extensive use of chromatic dominant 7th chords (D7, G7, Ab7) creating rich harmonic tension.
- Prominent application of the bII7 chord (Db7) as a tritone substitution, frequently resolving to the V7 (C7).
- Characteristic chromatic descending dominant motion (e.g., D7-Db7-C7), a hallmark of early jazz harmony.
- Inclusion of passing diminished chords (F#0) and non-functional chromatic dominants for added color and voice leading.
Improvisation Focus: Chromaticism.
Difficulty Rating: 4 (Advanced). The constant chromaticism and rapid harmonic changes demand sophisticated navigation beyond basic diatonic understanding.
