  • Frequent II-V-I progressions establishing new, often remote, key centers (C, F, Eb, D).
  • Rapid tonicizations via dominant 7th chords, quickly transitioning between tonal areas.
  • Unusual chromatic juxtaposition, notably the Bb7 leading to Emaj7, defying standard functional harmony.

Improvisation Focus: Navigating successive II-V-I tonicizations with appropriate arpeggios and modes.

Difficulty Rating: 5 (Advanced). The frequent, remote key changes and unusual harmonic movements require high-level harmonic and melodic adaptability.
