Harmonic Highlights
- Features extended dominant chains (D7b9-G7-C7) moving in descending fifths, creating transient tonicizations.
- Incorporates nested ii-V progressions, such as F#m7b5-B7 resolving to the primary dominant E7b9, effectively extending harmonic tension.
- Employs sequential ii-V-I movements (e.g., Am7-D7-Gm7-C7-Fmaj7) to modulate through related minor and major keys, enhancing harmonic richness.
- Utilizes both Bm7b5-E7b9-Am7b5 (minor ii-V-i) and Bm7-E7-Am7 (Dorian ii-V-i) creating varied tonic resolutions.
Improvisation Focus Mixolydian scales and their alterations (e.g., Altered Scale, Lydian Dominant) over the numerous dominant chords.
Difficulty Rating 4 (Advanced) - The frequent use of secondary dominants, extended ii-V changes, and temporary modulations demands sophisticated harmonic understanding and adaptability.
