Harmonic Highlights:
- Frequent use of chromatic diminished chords (e.g., C#07, E07) as passing tones or leading tones to diatonic chords.
- Effective deployment of secondary dominants and back-cycling (e.g., C7 F7 leading to Bb, or Bb7 tonicizing Eb).
- Presence of altered dominants (G7#9) and non-standard dominant resolutions, enriching harmonic tension.
- Temporary modulations through implied ii-V progressions (e.g., Gm7 C7 towards F).
Improvisation Focus: Arpeggios and altered scales over secondary and chromatic dominants.
Difficulty Rating: 4 (Advanced Intermediate). The frequent use of chromatic passing chords and altered dominants requires a sophisticated understanding of harmony and improvisation.
