Harmonic Highlights:
- Consistent use of diatonic and secondary ii-V-I progressions, notably F#m7b5-B7b9 resolving to Em7 (a ii-V-i to the iii chord).
- Temporary modulation to the subdominant key (F major) via the Gm7-C7-F progression.
- Inclusion of the chromatically altered dominant C#7b13, suggesting tritone substitution possibilities or leading to non-diatonic resolutions.
Improvisation Focus: Mastery of ii-V-I related scales and arpeggios, particularly navigating resolutions and temporary tonicizations.
Difficulty Rating: 4 (Advanced Intermediate) Requires navigating frequent ii-V-I progressions, temporary modulations, and a chromatic dominant, demanding awareness beyond basic diatonic harmony.
