Harmonic Highlights:
- Extensive use of diatonic and secondary II-V-I progressions, reinforcing the Bb major tonality while providing harmonic motion.
- Prominent tonicization of the subdominant key (Eb major) via a clear Fm7-Bb7-Eb6 sequence.
- Strategic employment of secondary dominants (e.g., G7 leading to Cm7, D7 leading to Gm7) to embellish diatonic chords.
- Inclusion of chromatic diminished chords (e.g., Db07 resolving to Cm7) adding color and tension before resolving to a target minor chord.
Improvisation Focus: Mastery of functional harmony and chord-scale application across various II-V-I progressions.
Difficulty Rating: 3 (Intermediate) – Requires understanding of common modulations, secondary dominants, and chromatic passing chords.
