Harmonic Highlights:
- Frequent use of ii-V-I and extended ii-V progressions (e.g., iii-VI-ii-V) establishing the C major tonic.
- Chromatic passing diminished chords, such as Eb07 leading to Dm7, introduce tension and smooth voice leading.
- Direct and significant modulation to distant keys, notably E major (a major third away from C), often achieved via ii-V-I.
- Introduction of complex, often fleeting, iiø7-V7b9 progressions, like A#m7b5-D#7b9, creating advanced chromaticism and altered dominant sounds.
Improvisation Focus: Navigating rapid, distant modulations with corresponding scale and arpeggio changes.
Difficulty Rating: 4 (Advanced) The frequent and often abrupt modulations to distantly related keys demand a high level of harmonic awareness and fluidity from the improviser.
