Harmonic Highlights:
- Frequent modal interchange, prominently featuring parallel minor chords (Cm, Ab, Fm) within the C major key center.
- Utilization of the Neapolitan chord (Db major) creating a strong bII-V movement to G7.
- Secondary dominants like C7 (V7/iv) and D7 (V7/V) expand the harmonic palette.
- The interplay between C major and C minor sonorities creates characteristic harmonic ambiguity throughout.
Improvisation Focus: Adapting quickly to modal interchange between C major and parallel minor sonorities.
Difficulty Rating: 4 (Advanced Intermediate). The sophisticated use of modal borrowing, chromaticism, and secondary dominants demands a flexible harmonic approach from the improviser.
