- Non-functional chromatic ascent from Fm6 to F#m6, creating immediate harmonic tension.
- Frequent and rapid modulations through a series of ascending ii-V-I progressions, notably to Db, D, Eb, and E major.
- Extensive use of altered dominant chords (e.g., F7b9, C7b9) to facilitate smooth, albeit complex, voice leading into new key centers.
- The blend of initial minor tonality (Fm6) with subsequent major ii-V-I sequences creates a sophisticated, ambiguous harmonic landscape.
Improvisation Focus: Navigating rapidly shifting ii-V-I progressions with appropriate chord-scales and altered dominant substitutions.
Difficulty Rating: 5 (Advanced) - The quick modulations, complex chord voicings, and numerous altered dominants demand highly developed harmonic fluency.
