Harmonic Highlights:
- Frequent tonicizations, notably the II-V-I progression to the subdominant key of C major (Dm7-G7-Cmaj7).
- Incorporation of modal interchange via the melancholic Cm6 (iv minor) chord, adding color.
- Chromatic alterations such as Eb7, functioning as a tritone substitution for A7, and the passing Bb07 diminished chord.
- Clear use of secondary dominants and extended II-V-I progressions (e.g., F#m7b5-B7b9-Em7).
Improvisation Focus: Chord-scale application, emphasizing arpeggios and targeting chord tones for temporary tonicizations.
Difficulty Rating: 4 (Advanced Intermediate). The frequent modulations, chromatic alterations, and modal interchange demand agile harmonic understanding and improvisation.
