Harmonic Highlights:
- Prominent use of tritone substitutions, exemplified by Eb7 (bII7) following Am7 (v) functioning as an altered dominant toward the D minor tonic.
- Extended pedal point over Fmaj7, featuring modal interchange and sus chords (Bb/F, Gm7b5/F), creating harmonic stasis with internal movement.
- Frequent V7sus-V7 resolutions (G7sus-G7, C7sus-C7) providing delayed dominant tension and adding color to the common ii-V-I progressions.
Improvisation Focus: Navigating altered dominant scales and melodic minor modes over the diverse chord qualities and temporary modulations.
Difficulty Rating: 4 (Advanced Intermediate). The blend of complex substitutions, a modal pedal point with internal shifts, and rapid harmonic rhythm requires sophisticated harmonic understanding.
